The price of ETH has gone from ~8 USD/ETH to ~90 ETH/USD in 6 months, but when I view transactions on the blockchain (example), I see that most people are still using the default gas price of 2e10 wei/gas.
Shouldn't we be lowering the gas prices on our transactions to account for this price change?
I have built a Dapp where low transaction fees are an important selling point. I intend to drop my gas price to 5e9 (a 75% reduction). Will my transactions still clear in a timely fashion?
UPDATE: I have been running transactions (as of May 5 2017) with a gas limit of 2e9 gas and they have been clearing in ~7 min.
