There are lot of candidates for 5x. Of course it requiares to hold them for several months.
I bought some coins 5 moths ago and most of them gave me 5x return.
The Bitcoin Cash could be a candidate. The price has already 2X.
5x means the price of each Bitcoin (XBT) BTC right now. I think is too much even for the most promising fork of bitcoin. or maybe after some years... Probably the price could rise to the top level of the past but can't really touch this higher pump.
there are over then 10k project and every day there are a new one, maybe there are undercover gems not in coinmarketcap
