Predicting the future is definitely hard and there is no shortage of talking heads doing just that. There was recently two billionaire Wall Streeters that put out $40T and $100T. Based on what, I don't know. But my newsletter editor was a VP for a big bank and then a hedge fund manager for 28 years. He is making his prediction using the internet as an analogy.
Boy do I wish I had more cash to invest. I'm managing my monthly cash flow to add more each month. If I had $1M cash, I would put at least 1/2 into cryptos right now. I say that based on what is happening in the background and the positioning that is happening with institutional investors, the wealthy and governments.
