A while ago (2017) there was this Dutch family that sold all their assets for BTC and is now traveling around the world. He had around 500k USD worth of BTC and expects it will at least make 5x in the next 3 years. In the meanwhile, they are living modestly and using 20% of their cryptos to trade.
Would you dare to do the same? Sell all your FIAT for CRYPTO?
I don't think so, every one of our speculations is different as well as knowledge. and I think the person you are talking about will experience a loss when the market is like this. and for the growth of bitcoin it will take a long time after accidents and prolonged corrections. I'm sure this year there is no significant movement in growth.
