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.
When it comes to btc, that's not that bad. It will grow with time, and you will get good returns in a few years. But it's not soo good with "badcoins," as most of them failed or will fail, especially those having no working product. So we must be very selective and careful with alts. Good altcoins may go up in future, as they at least have some ground except for pure speculation, but that won't happen with coins without a working coin economy.
