Problem with Bobby Lees views is, that he is one of the guys, who say that BTC is a "store of value", which is a horrific misunderstanding on what BTC is able to achieve or meant to be. We need to remember, that BTC was created to be a means of alternative way of payment. And actually looking into the past of BTC, we indeed see a positive trend in the long run, but at the same time, we see insane crashes. It wont be different this time and assuming, that yet another bullrun will follow this one, is speculation on the hope that other will buy at a higher prive, not on underlying value or usage.
I however agree, that buying $20 in BTC is not a bad idea. Because (worst case) losing $20 does not hurt so much as it would with $200 or $2,000. Because learning about investing in general is done best, when your own money is involved.
Edit: by the way - thank you for being one of the few people out there, who produce videos about crypto currencies, without putting your face everywhere.
