some good coins for us to hold for a long time such as Litecoin and Dashcoin because they also have good prices and enthusiasts in various cryptocurency markets.
What do you mean good prices?, both are done under 70% from january 2018. you mentioned Bitcoin at first paragraph I think it's the best cryptocurrency right now.
top 10 -20, I think they will bring more profit in the future.
Good Luck !!
I don't like holding Bitcoin, it is to risky to hold Bitcoin in long term while some altcoins are much more potential. I'm confidence in BNB, BAT, TRX, ETH. These coins will be profitable in long term.
IMO, altcoin you're mentioned are more risk than Bitcoin. good luck for you if you still hold those coin and perhaps get profit than Bitcoin.
