I am pretty sure that Warren Buffet also invested in many off the radar companies, which in hindsight now look like good safe long term investments, but at the time he had to put huge amounts of his money into them based on his own thoughts and calculations on the companies. So he actually saw the future value of some companies long before anyone else, which you could argue is quite the same as people investing in Crypto.
Don't be so certain, he pretty much invented 'value investing', which means he determines which stocks the market has undervalued based on their profits and other metrics.
Speculative investments like tech startups don't pass those types of tests, not least because they get floated before they've even generated a profit and will all fail the 'value' test.
He doesn't do seed investing or invest in any startups. I'm not saying he has never ever done so, but 'many' definitely not. He invests in established publicly listed companies which pass a value test.
This is why I said that times like this where money is flooding towards a specific niche is good for him, as it will mean other industries become under valued as they go ignored. He has literally proved the "follow the money" mantra completely wrong.... he goes where the money has forgotten to go.
He didn't even buy Apple shares until 2016.
He invests in the boring things like railroads, and utilities, and long established retail chains. Oh and agricultural land like I said! He bought his first piece of farmland before he finished high school, and has been buying it ever since.
I personally think that making good money in crypto and then switching to an asset which is guaranteed to hold value, like agricultural land, would be a good strategy.... doubling your money every decade sounds with the odd lottery win feels like a good investment to me... depends on your age I suppose....
.... if you are 55 and broke, and crypto is your only chance to build yourself a pension fund then sure.
If you are 30 then switching to a safer asset at some stage probably wiser than banking on bitcoin being here in the year 2048.
