All the experts mentioned are anti-Bitcoin advocates so you don't expect them to say you should put a higher percentage of your investment in Bitcoin, yeah definitely they will advise new investors to look in the direction of their traditional investments. So as long as you are investing what you can afford to put aside for a long term into Bitcoin, you are good to go through with Bitcoin volatilities because of the long-term perspective of the investor.
that's for sure, those that specializes on traditional way of business will never like to invest in a speculative asset like bitcoin or advice others to follow suit. so for us to make a good investment we should not follow some bitcoin critics, who don't see potential in bitcoin rather we do what pleases us, but we should try and invest what we can afford to lose in the long run. instead of me to follow this bitcoin critics, i better encourage myself with following people like Michael j Saylor who took bitcoin investment to another level.
