Even just a year ago bitcoin was useable... now the fees are about 10x what the banks charge. Seems like its changing from a peer-to-peer money system for everyone into yet another convenient way for rich people to exchange funds!
What went wrong> And more to the point, who is responsible? What can be done to fix it?
The fees are high because so many people are willing to pay a lot to make a bitcoin transaction. It is not a matter of rich or poor. It is a matter of what the transaction is worth to you.
The solutions are to make transactions smaller, enable off-chain transaction layers, and make room for more transactions, or perhaps to make Bitcoin less useful.
They could adjust the miner fees. But why? They're making more with higher fees. It's like 15BTC per block.
The fee is not set by anyone. "They" cannot adjust the fee. If you want your transaction to go through, you will have to push out another transaction by paying a higher fee than it. It is that simple.
How is bitcoin not peer to peer even if the fees are higher? it's peer to peer, just rich peer to rich peer.
If we want to solve this situation, we need segwit, then lightning networks.
Onchain transactions will always be expensive for small transactions. If we want to get everyone on board, again, segwit + lightning network is the way to go.
The problem with the Lightning Network solution is that it is
another payment system that people will have to adopt. It has taken Bitcoin 8 years to get this far, so we should expect adoption of LN to take just as long. A bigger block solution is
necessary in the meantime.
