Wide adoption with weak security is suicidal, sir.
Before trying to adopt demagogic methods to achieve wide adoption, lets teach them a lesson: this is money, better be safe than sorry.
I still don't understand this psychological barrier: if it is about tangible money, they buy the heaviest safe.
If it is untangible, they use straws to cover it.
And for the other user who talks about "test accounts", there is an awful amount of "test accounts".
No, sir, these users show a very very high degree of mental laziness:
