I would put only 10%, because nothing is for sure in crypto, if bitcoin can go up or go down, so if you want to safe your money I don't think you should put all in it. You can't be sure if someday bitcoin may drop considerably in price.
nothing sure , but bitcoin have teach us how sure it is ,
when the price of bitcoin $2 only , few people trust nothing to bitcoin ,
until bitcoin proven itself by go up extremely to 3,000% ,
you should learn from it , and put nothing doubt in bitcoin , invest as much as you can.
