Oh man, I think you should move all your funds to hardware wallet, since it's very safe. 44 Bitcoins worth $375.991,88 is very large amount, things again if you want put it all to online wallets. The cost is only $161,36 for Trezor T.
Everything can happen and it's unpredictable. Just holding and see the price in the future.
thank you for suggestion but i holding my BTC on online wallet since last 2 years and nothing happen,
i think i trust very much on blockchain and btw still waiting for boom to 13k$ or 15k$ for cashout my funds.
Just because nothing has happened yet it doesn't mean your money is safe. If I had that much bitcoin, I'd be holding some of it in a paper wallet, most of it in a hardware wallet and some of it in a normal bitcoin wallet.
You can clearly afford to do all of that if you have that much bitcoin.
People trusted Mt.Gox with their funds before and Cryptsy. Even big companies in this space tend to dissappear without a trace.
As Andreas Antonopoulos always sais. Not your keys, not your bitcoin.
