Should you just buy and hold Bitcoin, Ethereum or other cryptocurrencies?

Yes. Buy and Hold. BUT.

The last time the general public got into playing with securities was just before the dot com implosion. You may remember how everybody was buying Netscape, Webvan, Pets.com, etc. I remember one piece of advice which was: “When everybody, including the shoeshine boy, has stock advice, it’s time to get out of the market.” That’s what’s going on with Bitcoin and other cryptocurrencies. People don’t understand the fundamentals and they’re buying without knowing what actually makes the price go up or down.

Have you ever watched David Letterman interview a star he’s never heard of, but everybody in the audience knows who the star is? It’s like that. You can fake your way through it, but it can go completely wrong. So when it comes to these kinds of investments, do it like you do spare change. Do piggy bank money. Then if you lose, you don’t care so much.
