I tried to send some Ether for an ICO (my first ever) but the transaction failed with error revert opcode. Please see below.
I tired a couple of times but it did not work and also increased the gwei to 99. I dont understand how this will work as the ICO has receommended that we use 200000 gas limit max and 60 gwei (max 99) when sending ether otherwise the transaction would fail. And now the sale has ended so missed out.
Can you please explain how can I avoid this issue next time?
