If you are using the HODL strategy, then there is no point in choosing a currency. Keep in BTC. In my opinion, this is the surest and safest way.
why did you say if there was no point in choosing another coin? not the other one can also give us an advantage in the future I mean top altcoins
I meant that if you HODL for too long, then what's the difference in what to keep your assets. Although, if you look at everything globally and from the perspective of 2017, then the most profitable way at the moment would be to enter Bitcoin with its forks
