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?
In my city and in my country it is impossible to live only on the crypt. Apart from the option that for the crypt (as long as it can be exchanged for Fiat), you can hire a person who will do everything for you, including exchanging the crypt for Fiat to buy products for you.
