Consider Bitcoin as the base layer coin for the market as many of the exchanges price their altcoins against Bitcoin. Also, Bitcoin is often used as your base currency to get started with an exchange. What I mean by this is you will not be able to buy with your regular credit card, you will need to transfer in your Bitcoin and use that as the currency to purchase.
The crypto world is a uniquely perfect environment for arbitrage. As William Belk argues here, the combination of it’s distributed nature, regulation, security, availability, and anonymity factors means that the marketplace has many inefficiencies, and that “arbitrage opportunities will continue indefinitely.” For example, some markets pay a premium for security, geographical location, or simply because they don’t know they can get it cheaper somewhere else. In some cases, the price discrepancies across different exchanges can be as much as 43%.
Sometimes, it can be easier to enter a position than it is to exit that position. Certain exchanges are fairly illiquid: they don’t have enough buy orders to support easily selling off your cryptocurrency at a good price at any given moment. At other times, exchanges that usually have healthy liquidity might have really low trading volume — for instance, if you’re trading on a holiday or weekend.
Another thing I need to make clear is the type of trading I do - day trading. My base currency is Bitcoin, which I use to buy Altcoins like Ethereum, ZCash, Golem, etc. When I make a trade to buy an Altcoin with BTC, I could end up selling the Altcoin back for BTC within a matter of minutes or hours. All of my profits are converted back into BTC at the end of each trading day.
For stock market investors, investing in Bitcoin indirectly through a listed security such as an ETF, ETP, or trust may be suitable for those looking at taking a passive position. Active traders might find the limited trading hours and potential lack of volume a limiting factor that could hinder their trading. Overall, using listed securities that invest, track, or hold Bitcoin can be a viable alternative to diversify away from the risks of margin trading or safeguarding private keys when buying the underlying.
Bitcoin is different than any currency you’ve used before, so it’s very important to understand some key points. You can use them to send or receive any amount of money, with anyone, anywhere in the world, at very low cost. Bitcoin payments are impossible to block, and bitcoin wallets can’t be frozen. Actually, the Bitcoin network is unstoppable and un-censorable.
Speaking of the last two points, realize that crypto tends to be pattern based and tends to go in cycles. See “the cryptocurrency rotation” and “market cycles” for an in-depth look at what this means. You want to be in a coin before it starts its rotation, and then laddering out as its rotation ends. Likewise, in a perfect world you want to be in for the bull part of a market cycle, and out for the bear part. Near impossible to spot these trends in advance, but with experience you should be able to spot them as they occur and manage your positions accordingly.

Then there are the fundamental strategies. Some people say that fundamentals are the valuation of crypto, but it is challenging to value a cryptocurrency as there is no chart giving the earnings and the assets to derive a valuation from. Cryptocurrency is all about speculation, with one guy saying it’s worth a high price that reaches into the stratosphere while another says it’s worth squat.

We cannot say when you have lost a trade in cryptocurrency trading. If you’re not careful when it comes to cryptocurrency trading, you could find yourself gambling more than you’re trading, and eventually you might lose everything you’ve invested. Never invest more money than you are willing to lose. You should consider any money you put into a trade as lost.
Always learn from your mistakes. Never accept a total loss. Always evaluate the situation and try to figure out why it happened. Take that experience as an asset for your next move, which will be better because you are know more now than you knew before. We all start off as amateurs, and we have all lost money throughout out trading experience. In his first month of trading, Miles went from $1,000 to $300. I’ve lost a lot by selling at losses inspired by fear. No one is perfect, no one wins every single trade. Don’t let the losses discourage you, because the reality is they’re making you better trader if you choose to learn from them.
