My TOP-3 altcoins now are: HOLO, NKN and QKC. Great projects with huge potential and I will HODL till TOP-10 on coinmarketcap but DYOR!
funny "buzzword" post
HODL, TOP-10, DYOR!
(not much input on the coins suggested)
on topic, it's difficult to say I think since there's different levels of risks.
investing everything you own into bitcoin is far more safer (while still could be risky) compared with investing everything in a new, although promising, coin.
one should always make sure you trust what you invest in fully atleast..
