Time factor is very important in cryptocurrency market, time determine what we invest in, as at the time you post this thread, altcoins were down and the best thing to do is to stick with coin which the future is certain and that is bitcoin. Now, things have change, we now have people investing more in altcoins than bitcoin now. It is not about boycotting altcoins, it is about timing.
unfortunately they don't know that altcoins have a higher risk than bitcoin because altcoins can get a lot of benefits but the price movement is very unstable and can cause losses when the price collapses instantly because altcoins have price movements depending on the project they have.
