BTC
ETH
WAN
MAN
ZRX
Other than that, just flip shit in szn and use Bitmex.
Edit: some other exchange/dex coins too, all of these are better than amost anything else given it's a good ex/dex and token has value
I think BTC and ether are two coins that most everyone holds in their portfolio.
And while the other three are also good coins, i especially love ZRX i would rather hold the privacy coins Z cash/monero as i feel they are safer to hold, and are again pure currencies. Monero is my all time favorite
As for ZRX perhaps make an even split between ZRX and BNB which also plans to go the DEX route and establish its own chain in the future. The advantage of BNB being that it already has an established/largest centralized exchange.
