There are so many exchanges are going on with false traffic volume. I have gone with these exchanges and experienced some problems. Now I am going to tell one or two experienced with you. Baz token in etherflyer is not from traders it is false trading because there is no buyer and seller on the price they executed.when you trade their ongoing price will fail. Same case with p2pb2b exchange when I trade P2PS coin. Pgpay coin price is different from probit exchange.so today exchanges are really not doing great things.
I think perfect analysis of situation is definitely best weapons in trading. Analysis means you should know their project, community,their hard working skills, their management.their team , their ico, after done these speculation you can enter to market and try to make some profit. But in the crypto world Cryptocurrencies are increasing every time so very difficult and very risky to trade so do analysis and buy on absolute low point.
It is basically trader call how much money he want to start with but In my personal experience the minimum coin to begin trading altcoins is about 0.01B because you should hold some btc to trade for some profit. Trade with these bitcoin and trying to accumulate some extra bitcoin. If you are a beginner,it is better to start with 10-20 dollars,invest them in 3-4 tokens and see what happens. Bitcoin trading is high risk and gain so you should be aware of the fact.
There are lots of exchange going arround. Every exchange has different system.some has to do kyc for big withdrawal, and some has even for short withdrawal. But Binance is the best exchange where you can withdraw 2btc ammount without kyc. So everyone can join this exchange and make some high profits.
Not in crypto ,you have to get security in every aspect of life. Without security you can loose what you earned with hard work. In Cryptocurrencies you have to secure your fund because people has earned this Cryptocurrencies with lots of afford.some people invested their hard work money for life to make better. If they not secured this, they can loose their crypto by hackers. So play smartly be safe.
