increase block size may injured bitcoin node ... because of the pollution of trading (high trading).
people that need speed ... must build sidechain (or offchain strategy like bitpay ou coinbase).
i don't agree to increase block size except if it has a limitation ... (like 10MB).
Trading is going to happen regardless and transactions are going to increase if we want to keep bitcoin how it is today we will need to increase the block size or start expecting a long block queue for everyone. There is a limitation set at 20mb so we won't have to fork off it for a very long time and that gives us time to adapt. Blocks won't automatically be 20mb either just have the option to increase that high and only if we need it, if we have that many transactions and the same 1mb there would be a 20 block queue so you would wait 200 minutes for a single confirmation (over three hours!)
