It's a false sense of security, nothing more.
Even assuming you trust Binance to actually have a fund as they say they do, it will only protect against small attacks against Binance itself.
If your account is hacked, it doesn't help.
If Binance experiences a large hack, it doesn't help.
If Binance go bankrupt, it doesn't help.
If some rogue employees clear them out, it doesn't help.
If Binance are shut down by regulators, it doesn't help.
If they are hacked for your personal information and KYC documents (again!), it doesn't help.
There is no such thing as too big to fail in either the fiat world or in the crypto world (e.g. Mt. Gox). Binance can go on and on about SAFU, but the bottom line is that any coins stored on any exchange are at constant risk.
All of this, and although I hate to say it, is where the more regulations will get more investors, comes in.
@o_e_l_e_o is correct all of it does nothing.
But, and I have said it many times over the years, this is where big government makes people feel all warm and fuzzy.
I don't really care what happens to my bank. The FDIC will cover me to $250k
I don't really care what happens to my brokerage, the regulators cover me to an amount larger then I will ever have.
Yes it costs me money, since the banks and brokerages have to follow rules and that costs them profits, but it is what it is.
I can figure out a lot of risks and stuff myself in the crypto world, and do not want the government sticking it's nose into it.
But....there are a lot of people who can't and want that security and won't invest without it.
Is there another solution? I don't know.
