There are a whole lot of coins out there in the market that will and is capable of giving good profit returns, so are there coins that whence they go up just one time, they die off, and when you don't sell at that one time high, it becomes a shit coin in your wallet, which never resurrect again. That is why, I invest mostly on the top crypto currencies on the long term, so as to avoid much losses. For the short term a few collections on EOS, ATOM etc are some I invest on, while for in and out, I take doge, polkadot, LTC, Etc, and coins listed on binance that gives me some good returns in short time trade.
