Bitcoin is the a digital currency so is it easy to use unlike a physical you need to carry it everywhere bitcoin is a digital currency so you can access your bitcoin everywhere just using your phone and a access in a internet also thief cant steal your bitcoin. Main thing is it is easy to use in the future you can pay in just one click.
Although it is convenient to use we still need physical money in small expenses. I love bitcoin its capability, convenient and the capacity to earn more just like any passive income. I can buy things online without showing my credit card as proof of payment which is too risky nowadays.
What do you mean by showing proof of payment online using credit card? I don't inform that some online merchants require proof of payment using credit card since the transaction is almost the same when you use bitcoin as payment. Their only difference is just anonimity features.
@Makolz26 didn't say that he needs to show first the proof of payment online using credit card because it is the other way around, you might want to reread it again for your to understand, it seems that you just misunderstand what he said. Because the truth is we don't need to show this proof of transaction in bitcoin, maybe there is a chance that you have to show it, for example, you are going to have a transaction with someone for the first time, and you wanted to know if he is really a legit one, let's say that he wants to buy something to you, of course you are going to ask him first the proof that he already paid you before you give him the product.
But most of the time, it is not needed, especially if the Signature Campaign is going to pay us, we don't need the transaction proof anymore to confirm that they already paid us because they will not scam us just for a very small amount of bitcoin.
