Crypto has its risks as well beneficts, use bitcoin for trading is one of the best sources and easy way to make more money, sure isnt an easy task and not all of them will lead into the sucess and profit. There are a few altcoins being able to loose and recover while others just get dumped and left or used to pump and dump, each person should always search about the coin and the use of it.
Trade in alternative coins is very dangerous. Especially if you do not have experience. Therefore, I recommend newcomers to trade only bitcoin and some coins from the TOP-10
In contrary, for me trading is one of the best source of income because we all know that alternative altcoins are worth it to buy. Some traders are earnings profit double or triple of their capital, that's why more people are encourage to join in exchange sites. definitely I'm one of the traders but I have lack of knowledge to be one of the best traders in bitcoin community.
If someone getting profit it means someone else is suffering losses. You could be on both sides with almost equal probability. Be careful my friend! Don't let greed to blind you
