How do I determine correct GAS in MEW for contribution? It's defaulting to 100358. Is that correct?
As far as I know, you need to put gas limit of 250 000, and the price of gas 25. This way you will be able to undertake your investment without any problems.
The MEW wallet automatically sets the required amount of gas limit, you only need to put the price of gas. Put the gas price above 30 and there will be no problems with the transaction.
