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.
