I am also looking for good altcoins for investing. But ı could not find seems promising to me yet. So ı decided to hold my money in bitcoin until it will reach $20000 again. After that ı can invest different altcoins for long term.
I also hold the bulk of my capital in bitcoin. But besides that, I've already bought a few coins from the TOP-10. It seems to me that these coins have a very large potential.
