Why does MEW usually have trouble? Because of so many users, aren't there?
can you explain what problems you have experienced in your MEW?
the solution is this, depending on the problem you are experiencing!
1. If your MEW is experiencing congestion you cannot access, then correct it carefully if there is something wrong with the code.
2. If your MEW is hacked, then fix it immediately by downloading the new Mew. that's some of the solutions that I offer, hopefully useful.
