2. You should know that bitcoin transactions are irreversible once confirmed unless the receiver decides to send it back.
And the possibility that the recipient will return it back to the initial wallet sent the BTC is very small. Because sometimes, we may not realize how much BTC we have in that wallet at that time. Unless it is a large amount, then it will be a really confusing one, whether to keep it without caring about the sender's feelings or immediately return it with a transaction fee deducted. So I thought, what would happen to us if we experienced the same thing, receiving transfers from unknown wallets for quite large amounts?
So, this is clear, whoever, we must be careful when sending Bitcoin or even altcoins to certain wallet. doing double check to the wallet address several time before clicking the transaction is a must. no need to hurry up in careless ways.
4. You should know that despite bitcoin not been any countries currency, some countries might still attach tax and other commissions.
Just like on my enagra. Honestly, Bitcon is indeed legal as an asset commodity, but illegal if used as a payment transaction tool. However, if it is related to taxes, yes, we cannot escape taxes. and we are even obliged to pay taxes directly when we trade on local exchanges which are under the regulations of our government.
