I truly admire Warren Buffet but calling Cryptos a gamble is disappointing given how he has done the same multiple times. He sold put options when the market tanked in the financial crisis and that wasn’t a gamble? He has made most of his fortune with the acquisitions of insurance and reinsurance companies which are highly dependent on whether catastrophic events occur to make profits; is that gambling? No, it is putting money in upcoming industries that the world needs.
