$400 via WU is what?
I think it's 10 bucks or more to be 'instant' which is 15 mins or so
In order to do so I would already have to have 10 bucks in the first place. In order to make a fair comparison (same as the other way round) you'd have to take into account that I have to convert some BTC to USD first, which will take me a couple of days at least (before it arrives at my bank account).
Bitcoin
Well both have to have wallets
Of course. Just like both also have to have dollar-wallets and dollar-bank accounts and dollar-credit cards or paypal accounts if you want to send dollars between each other.
Sender has to have at least 400 worth of btc to send, if not it takes 3 days or so to 'fund' the wallet via bitpay and that costs 12 bucks or so
I dunno how messed up things are in the US, but here in Europe I can buy bitcoins almost instantly, online. I make a bank payment and I literally have the bitcoins in 5 minutes (the seller receives my euros a few days later).
Secondly, it's a weird comparison if you are going to take fiat to bitcoin into account at all. Why not the other way round? If I want to send a person dollars, I have to sell some BTC first to convert that into USD, it's gonna cost me x bucks and y days.
They got btc not cash, now let's see how to get it out
Find a local and hope you don't get killed over $400 bucks and pay what 5% or 10% or 20%
Receiver has bitpay too, so then what transfer to a bank to withdraw and that's 3 days or more and then what are fees
At this stage to send money INSIDE USA I don't see btc as a viable way to actually do a minor task
You are still way too "dollar minded". The whole idea of Bitcoin is
we don't NEED dollars anymore. We now have a new kind of money that we can all instantly send to eachother, spend in IRL stores or online on whom and whatever the hell we want, without ANY dependencies or 3rd parties or middlde men or costs or delay or arbitrary rules or authorities or bullshit with accounts being frozen or transactions being blocked or anything. Why the hell would that not be viable within the USA.
