I do believe that security that these companies have for their coins is huge. However I also believe that they have insurance for these type of things as well, meaning even if somehow they get their things stolen then they will be paid that much amount as well. Which could be even good for crypto, how?

Well, let's assume that they do get hacked and all of their coins get stolen, that means insurance will pay them that much and they will likely to use that to buy some more, which is awesome and I like that and it will increase the price of it, on the other hand the stolen coins would be a hard time to spend or sell as well which means it will not be dropping the price too much, or even if it ever did then it won't be all at once. So, this company getting hacked and all that money stolen could mean an increase in the price of bitcoin in the long run.
