We need to accept the facts that it's very difficult now to see a coins doing x10 x20 or even doing 50% returns on investment in this bear period. And nobody knows when the bulls will come. Therefore, it's will be advisable to exist when your coins do 20% returns or even less. I know some investors will not be satisfied with 20% but we need to be objective and understand this bear period will last longer than expect.
You won't see it at least for now because the current market is still low, although there are some rising movements.
Even achieving 20% returns will be hard because there are no sign of bull market.
for now, i think it is better for investors to hold their coins, except they are just a traders.
