my most favorite coins are bitcoin and ethereum. they choose big to invest. i prefer these two coins because it is good to invest it can be longer or shorter. and their graph movements are very fast to sell and buy
Obviously what you are saying is that for now it still cannot shift bitcoin and ethereum. it's true that the up and down movements are very unexpected. but because the investment that we will do is very profitable if want to carefully analyze it well.
but if I want to find other altcoins, I refer to those in CMC.
