When buying coins, and especially with Bitcoin, you will notice that your purchase is in decimal. A Bitcoin itself is relatively expensive, around $10,000 at the moment (as of 15th Feb '18). If you were to purchase say $5,000 of Bitcoin, you would at today's rate be purchasing around 0.5 of Bitcoin. Do not ever worry about this; Bitcoin operates at eight decimals places. You do not need to own a whole Bitcoin or any coin for that matter. Consider it like pence in the pound or cents in the dollar, but with more decimal places.

With the KuCoin exchange, you’ll also get an is an easy, hassle-free experience along with different popular as well as rare cryptocurrencies such as DragonChain, IOTA, etc. If mobile apps are your preference, you can trade on KuCoin easily as it has apps for both Android and iOS. In order to go ahead with trading in KuCoin, you can deposit any crypto initially and start immediately. In terms of fee, KuCoin also takes 0.1% per transaction, half of which can be taken by you through the unique dividend system offered by the exchange.

In contrast to Forex or stock markets, crypto industry have much more risks for traders and investors including scam exchanges, hacker attacks, delisting of tokens and the others. Cryptocurrency market is volatile and coins have no underlying value meaning they may cost either $100,000 or $0 depending on demand and supply. Nobody can predict today the price of Bitcoin for several years.
Speaking to CNBC, the crypto trader claimed that other coins might have been overhyped as the progress in distributed ledger technology is slower than people expected. Smith said that, “They got really excited about all these other tokens and use cases. And all of the sudden you saw all of these smaller tokens, as people got excited about them, massively outperform. We got way ahead of ourselves.“

Watch out for odd Altcoins and ICOs. The market is tricky enough with the major coins, it is even trickier with odd alt coins and ICOs. Yes, sometimes you can buy these low and see insane gains. In fact, getting it right is the best bet in crypto. The problem is, almost all the odd coins down the list and ICOs will spend the majority of their life being near worthless. Then, you may see a short time span in which these coins preform well. You would think that you would be able to take profits then, but so many people do not. After that one event these can end up in the graveyard. Yeah, you could make it big on low cost alts and ICOs… but I’ve seen more than a few people lose money. Be careful bottom fishing, Bitcoin might not make you rich, but it is a way less risky bet than coins further down the list.
UPDATE: I do not recommend paying to enter a Cryptocurrency mastermind group – I’ve tried a few and found the ROI to be disappointing. I am now focussing on growing my portfolio passively utilising a cryptocurrency trading bot, the renowned Notorious Bot. Having a bot that trades for me, without emotion, using an advanced algorithm, allows me to grow my portfolio in the background without it cutting into my time or stressing me out. You can familiarise yourself with the basics of cryptocurrency trading bots here. 
Especially for traders dealing with fairly large amounts, multiple, small entries and exits over a fixed period of time (dollar-cost averaging) can help obtain a good price for an asset over an extended period of time. Consider using time-weighted average price trading: specify n, t, and p such that you buy or sell n of a cryptocurrency over t hours for an average price of p.

No coin will go up forever, even Bitcoin has very good days, and then some really rough ones. The crypto space is ever-changing and evolving, with new opportunities coming up every day. If you believe in a coin, holding it for long-term returns is a good approach, but if you are looking to make money by trading, you cannot have emotional attachments with any coin.
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
