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?
Of course not. Fiat money is supported by the state and production capacities, the cryptocurrencies, are mainly supported by interest from the community. It's too risky. I would still diversify my savings.
