Some altcoins perform good resistance against bad market condition, but most of them just pump and dump. Recently I was trying to do daytrading and I saw that big investors looks like they just playing with some altcoins. They pump for few hours then dump it again, people who have big hope with those altcoins stuck at expensive price and don't have any idea when will the price go up again. Durring this bear market, traders only care about profit, I was learn the chart and realize that people looking for good position and sell it immediately at higher price that predicted before, and using this pattern is very easy to make profit about 9% - 12% every three days. But the price of the altcoin keep fall at the end. But some altcoins are very strong, those investors can't do the same thing to those altcoins. For example is TRX, I don't see pattern like that in this altcoin, TRX price usually goes in line with  Bitcoin price. This altcoin have big chance to grow faster because it seems that it's price will rise when bitcoin price rise and it keep rise when bitcoin price fall because some bitcoin investors will looking for some altcoins to invest as they get profit from bitcoin. There is a note from me, when this altcoin price rise like a rocket just remember that the price will fall again. So don't blindly hope for this coin to surpass bitcoin, it's just like other altcoins but stronger. This is how the market works. Always prepare a good strategy before trading is the best way to avoid loss. That's my opinion.
