if my opinion is actually in 2019 there are also lots of good coins to hold now, because now market price developments are also increasing, so I think I will save some altcoins for the long term, for me EOS, BNB, LTC, NEO, ETH, THERE AND BCH,
I think some of the altcoins that I hold also have a good future, so I'm sure they will also get better profits in the future.
