For me, cryptos is somehow a danger and an opportunity. A danger because it is still not fully protected and could still be hacked by the professionals and the most dangerous is that a country whom fully use crypto as their primary currency could all fall down from richest down to rags of no money at all due to crypto hacking. And it could be an opportunity as it was a great mode of payments with transparent and much faster transactions, and also a good source of income due to trading and mining.
