According to https://bitcoinfees.21.co/, it needs 420 satoshis/byte to get fast confirmations. Anyone know why the fees are going higher and higher?
Because of Bitcoin Core developers incompetence.
Not really a need to bring that up here especially since there is already a solution that was brought forth but there are certain pools who shall remain nameless that don't want to participate. If you were a miner would you like 420 sat/byte or 25 sat/byte...? It all comes from greed.
