Hello! To be honest, I'm so tired of waiting for transactions. I use changelly and I have to wait for my transaction for 5-30 minutes and that's exhausting. Do you know exchanges with faster transactions?
I think it's ok for wait 5-30 min. Basically it's happen when network carry too much load. I remember once when my token take to transaction was 18 hours. I think Binance is more faster than other exchange. And i think now days eth based tokens are faster than bitcoin or other block chain token.
And one more think, miner try to solve or take those transaction which fee is big amount if some how your gas limit is low then some times it take much time to transaction. It's a regular thing if network carry too much load then you have to wait for while.
