That's because no single person or group of persons is or are in control of Cryptos, it's called Blockchain technology
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
Not necessarily. There are also centralized cryptocurrencies out there such as XRP who fails to fall under this definition of 'blockchain' that you pertain 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 naira and no one will know about it
One way or another, someone will have to know about the millions that are missing on the cash flow of a company. Ever wonder how some 'documents' regarding such transactions are leaking every now and then?
In the Crypto space, such is not possible because any kobo that leaves your account can be monitored and traced by anybody at all
So stealing with Cryptos is almost not possible
Stealing cryptos is pretty much possible with a lot of gullible people and a not-so-secure exchanges that are being exploited by hackers. Cryptographically, cryptos are pretty damn secure, but when you add the human element onto it, it becomes pretty much vulnerable, too.
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.
This may only be the reason why people are trying to close in to the crypto space in an accelerated pace. The rewards and the profits that they are getting from crypto is unmatched no matter which asset class you compare it to.
