Being in crypto for  a while. I know  how much damage to your live may be caused by sudden unexpected inflow of  cash. 
Thinking about  this  more I came  to a certain  conclusion. I think  that issue may be solved by  contract platform like  ethereum and  others similar.
This service may work as  follows: let say I put in a ethereum contract quite a big sum of money . Contract works in such way that it is  using this money to pay gradually over constant period of time small sum  to  specified address. Contract is doing so until it  is  exhausted. It works like  retirement fund.
Although it seems there is no visible benefit  to  that, from  my  personal  experience it  give you great  tool  to control our  desires, by putting some  delay  mechanics to  riches you have
Implementation seems to be easy, so in not so distant future I plan to  implement such  contract for personal usage
