Nah, I think you just don't understand how bitcoin work. Granny can give the address to Timmy before she sleeps.
If Granny were using a bank account, she would need to give her account information before going to be also, otherwise she would have to woke up in the middle of the night. lol
Your another of those that telling people that Bitcoin is Jesus and the rest of us are morons ... you are blinded if you don't see the problem ... or you invested in btc
Well here is another problem for you :
Minimum Requirements
https://bitcoin.org/en/full-node#costs-and-warningsBlockchain size:
https://www.statista.com/statistics/647523/worldwide-bitcoin-blockchain-size/Each year to run a full node you need more space and more processing power ,do to fact more transactions are added to the blockchain etc ...
That means avg tech guy will not be able to afford to host a bitcoin node or to mine btc... even now it is expensive ...
So who will host the nodes and mine ? The big corporations and after govs ...
The bigger it will get the more power the govs will have ... do to fact they got computing power ...
Now it's just a matter of time ...
So here is the irony : Bitcoin from a decentralized coin will become centralized ...
The idiots that will have btc in their wallets when corporations and govs take over will have a bunch of worthless numbers .
Bitcoin is a Ponzi/Pyramid scheme.
This is the truth !
