In Vietnam, the legal framework is not complete, the exchange activities, payment by Bitcoin is not considered legal. If any dispute arises, it may not be accepted as a means of payment.

I think this is a good idea. The bicoin hardware wallet will be the right choice, even it's easier to use than a credit card.

 The price will most likely rise again soon! I hope so.

The major benefit of bitcoin is to earn money to have people income and you can use bitcoin in making transactions and in shopping online, you can also depend in bitcoin.

ETH and Ripple
