It's a decentralised system meaning money sent or received from or to an account can be seen or monitored by everyone or anyone who wishes to
Unlike your normal bank that has CEO who decides how he wants to run his business, he can collaborate with the president to Syphon millions of dollars and no one will know about it
In the Crypto space, such is not possible because any amount that leaves your account can be monitored and traced by anybody at all
So stealing with Cryptos is almost not possible
And again, Cryptos rise/fall every second, but the chances of rising is higher
That's why Bitcoin of $10 today can turn $14 in 14days time but your $10 in the bank will reduce to $9 after bank charges
So a time will come when everyone wouldn't want to be cheated again by the banking system and would move to using Cryptos for Saving money and other transactions.
Well people who understand crypto will definitly choose cryptocoin rather than using fiat, because it's decentralized system make it's unique and most of coins now can process a lot of transactions now and it will arrive at short time also ofc with low fees . And the other things we will keep as anonymous when using cryptos despite a lot of centralized exchange ask for KYC nowdays, It's now mandatory I guess .
