Hi Guys

How can I set the GWEI price in MEW higher than 99?

And then Ive got an other question: When I participate in a ICO where it starts for example at 12.00. It is very popular and I need to be fast with a high gas price. Is it possible to start the transaction before 12.00 - lets say at 11.55 and the ethers will arrive at 12.01. Will it be successfu or rejected?

Thanks guys!
