Long term, ALT dominance is going up, there's no question about that.
The hard part is knowing which ALT will outpeform BTC.
ETHBTC for sure but apart from that, other ALTS take turns.
So it's a trading game. The safest bets are the top 10 ALTS but those change too. Top 10 ALTS 3-4 years ago are completely different than today!
Ethereum will do well vs BTC, there's no question about that.
Which other crypto will outperform BTC in the long term?
