It's difficult to find a potential altcoin that can increase 100x in this year, but if you hold for long term or wait the bull market, binance coin and bitcoin cash are good for long term investments.
it's very difficult to find the existing coin that can go like that but it's possible to search the best new coin. Some latest IEOs bring huge profits to the investors right now. The only chance to bet on the new coin.
The promising coin already worth a lot of money and that's impossible to go to the 100x or even further.
Most IEO projects are profitable for a short period of time and will certainly depend on whales so you need to be more careful. In the crypto market, the coins that can be x100 are usually new ones that are less popular, so I spend a lot of time researching them. Of course there is big risk, but if you find the right coin, you will become rich in a short time.
