Our world changes constantly and if you want to move with the times and to progress along with the rest of society you should accept bitcoin. No problem in using usual money as well as digital currencies if it gives you comfort. If bitcoin disappears it doesnt mean that fiat money will grow.
Yeah your are definitely correct, crypto currency gives us comfort especially if you have relatives far from you you can easily send them bitcoin fast and easy with minimal fee. And they can convert that on local fiats and use it. It is more efficient than sending real money that has high sending fees.
