I was stuck at 11% synchronization for 3 weeks, then a few days ago it started working. I assumed the new devs had resolved whatever issue was causing the problem.
I have always had the wallet synchronized with more than 53 connections, as I say you have never presented problems, Because I never sold my coins, there are many who will repent for having sold millions of coins to 0.00000001, it was better staking, now the price is increasing
