Well, bitcoin could be a little less volatile. If I was receiving a payment of a million $ as a liability and had it in Bitcoin, I would already have incurred a loss/gain on the deposit. No one wants to receive large payments in bitcoin. Also, what if you forget your seed?
Why would you forget a seed with a million worth of Bitcoin in it?
I don't have that much but I will never let my seed be forgotten or lost, the same with my private key. Either way, if that is transacted, it will be a talk of the community. It is true that Bitcoin is volatile, that it would dump and pump in a certain time but with a lot of people supporting cryptocurrency, I don't think it is that bad. People are taking advantage of those movements to earn some profit in the long run.
