Simple two questions, any advice as to whether to be concerned to either transfer the coins to a hard wallet from Coinbase prior to the Aug 1st or not really needed?
2nd, is this Aug 1st situation going to kill the value of Bitcoin?
I seriously doubt anything will be happening as not a single miner has signaled yet for 'uasf'.
the segwit2x team led by Jeff Garzik is coding a scaling a solution.
that being said, Its always better to HODL your own coins...Coinbase customer service is terrible. If you ever have an issue, it could be a long time before its resolved.
