I think that is a little risky. It could be a better idea to divide it to couple. Keeping all of them in one place is risky no matter what. I don't know what is amount of money your are talking but still it would be better to split it 2 or 3.
The risk associated with it is very big, because just think about the present price along with the price a month ago. The difference is much big and if one has kept his entire salary in crypto wallet, he'd have ended up with a big loss which might have affected his living. Better is to have a diversified plan to get rid of loss happening as a whole.
