I will only recommend 3 altcoins that i think you can hold it safely for a long term,
1. ETH
3. ADA
those three altcoins are going to be huge in the near future i think not everyone know a lot about those altcoins.
but still, i'm very confident that those coins are gonna skyrocket at least in the next 6 months.
that's what i'm hoping for.
I have been having these two for months now and i must understand their potential to hold but not this one
ARPA
but this?
