First of all, thanks for the reply.
It's basically a post and not really a reply to my post, but still. I appreciate the attention

I don't see why it's pessimistic. I can short cryptos when they go down and make money.
It's pessimistic if you're a hodl'er.

I agree, nobody knows, but some educated guesses make more sense than others.
Some theories/strategies that have been proven over and over again make the educated guess even more educated.

How do you know there isn't enough data yet to predict the cryptos? How much data is enough? Not having much data is not a reason for volatility. It's very volatile because it's a relative small market where FOMO and FUD go hard.

I agree. When the correction is over I see new all time highs voor BTC and most altcoins.
