Trading on low-volume days in the market could incur substantial slippage. People who make trades — especially large trades — on low-volume days often will not find many partners on the other side of the order book willing to make that trade. The result is that they could end up paying much more for the trade than expected, incurring slippage in the process.
You could try this instead: Be sure to keep reading crypto news and price analyses — not just staring at charts. Even though you shouldn’t give in to the FOMO and FUD generated by many crypto articles, you still need the news in order to stay apprised of market conditions. Also consider setting stop-loss orders to ensure that your losses will be mitigated in the event of something like contagion. 
It does not matter at what point you enter the market for a coin if you believe in the long-term. Bitcoin was once expensive at $1; it was then expensive at $10; people could not believe it when it hit $100; people could not believe it when it hit $1,000 and when it hit $10,000 they called it a bubble. It could be $25,000 next year or drop back below $5,000. My only advice here is not to chase something during a parabolic upwards move because it will almost certainly come back down. 
A small number of cryptocurrency pairs. It is true. You will not find any altcoins from above the top 20. However, Bitstamp offers in its turn the possibility to work with hybrid pairs including USD and other fiats. The exchange can be used as your pass into the world of altcoins as you may buy BTC or ETH here and then transfer those cryptos to other exchanges with a wider range of pairs, which do not support fiat money.
Security Key – I recommend taking this key, and saving it in three places. Write it down and store it in a book or journal, bury it in your email, and take a picture and lock it behind a vault-app (I like to use Keep Safe – it’s free and secure). This ensures that you have mutliple means of accesing this important key. In case you get locked out of your account, or lose your phone, this is the only way to get into your Binance account. Heed my advice. This is like crypto-insurance, and you never need insurance until you fucking NEED insurance. Take the steps, and make sure you do it right – you won’t regret it.
You’ll find that different exchanges cater to different markets. Today, most countries have at least one cryptocurrency exchange specializing in their own currency. There are exchanges that can accept New Zealand Dollars in exchange for bitcoin, for example. Other exchanges are known for certain pairs. Bithumb, for example, has particularly strong liquidity in the ETH/KRW (South Korean Won) pair at the moment (and it’s easily the most popular cryptocurrency exchange in Korea).
"You can buy bitcoins once a week for 500 or 1,000 pesos, regardless of the price; The average price of your investment in bitcoins will be very good, since although one day purchases more expensive and the next cheaper, the long-term average will be better than saying 'today the price is good, I will buy for 50,000 pesos' but you can That tomorrow may come even lower; If he buys regularly and leaves it for a year or two it is not speculation. "
I prefer to trade on decentralized exchanges. For myself, I made a choice in the form of ethnermium.сom. They have a huge number of coins. There are no minimum restrictions on trade and fees are so insignificant that you will not notice them. I also think the advantage of the easy creation of a wallet like MeW and easy integration with metamasks and a high level of security
Keep a critical perspective on the data that exchanges are providing you: technical analysis is only as good as the data it’s analyzing. When looking at volume numbers, for example, ask yourself: What’s the source of this information? Has it been validated? Could other factors be skewing the number? Beyond just looking at the numbers, it’s important to understand the meaning of those numbers: what they imply, and what biases could be influencing them.
Litecoin, like all major altcoins, has depreciated substantially against BTC. This decline has been precipitous and nearly monotonic since May, with even the slightest corrective rally sold off immediately. However, we may find solace in the fact this pair appears to have found footing around 9070, which appears to be a very significant level of support. In the ...
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
