However, if we are talking in 2017, I have already proved that diversifying in altcoins is a good strategy, you guys just won now because altcoins are struggling, lol..
It's a good strategy,
if you got out immediately on the top of the bubble. Buying coins/tokens at the bottom and needing to sell at the top isn't "diversification". It's speculation/gambling.
I hope to prove you wrong at least 5 years from now.
I'm going to wish you the sincerest best of luck. You're going to need it.
