If there is a charity accepting bitcoins do you prefer to give some of yours 
Me: I will if there is, but for now I don't have yet.
EDITED:
Yeah it a hassle for now.
Another question: But what if there is fiat will be disappear in the future and crypto will conquered the world and all payment transactions will be on blockchain system?
So is this applicable right?
Sure in future we dont know what will happen in our transaction system, i believe whether its applicable or not its only time could tell, but i believeit should be applicable and people will adapt with this coindition as long as its safe and could make transaction easier.Me: I will if there is, but for now I don't have yet.
