Yes and no. One is a technical issue and by now, no brokerage or wallet should be hacked. The other is a moral issue, just how much can you trust your unregulated online broker...
So it comes down: do you trust the technology AND do you trust the decentralized nature?
If hacking still occurs due to new types of access or tricks (I doubt), then cryptos are still not ready for the general population.
The technical issue is that no computer system is secure. Not a single usable machine. The more usability and utility, security trend towards worse and worse.
So it comes down to: How gullible or downright stupid are non-technical people?
The incentives for keeping secrets online are perverse, and distributed blockchain technology doesn't really adress the fundamental weaknesses in information security as a concept.
There's no 100% security, nowhere or at any time, and can be indirectly found as a depressing function of usage, usability and utility.
The only reason it's not too big a problem already is that we haven't
yet made it worth the effort to crack all security measures.
Trust is lack of security, especially for something as fundamental as a distributed blockchain (ledger).
If all that is required is to copy some bits and bytes in order to"steal", then securing against that will be a lost cause. Doesn't mean people won't trust it, just that it's a misguided trust that can blow up in your face and rip it off, at any time with no recourse.
This reminds me of DRM and the copyright industry: see how well they fare along the same ideas of restricting information flow. In the longer run it's a losing battle.
Not a short-term prediction though. LOL!
This is all Bullish, ofc.
