You're right. When I provided liquidity as low as 1 ETH, Gas fee was about 5% (one way) and I dunno how much it will be when I withdraw back. That's why I don't do short term transactions and invest only if I feel I may get much higher profit than what I incur on Gas fee.
I'd like to use other cheap transaction systems like JustSwap on Tron or DefiBOX on EOS but I don't have pools for my preferred tokens there right now.
Let's hope Steemit wallet is integrated to Tron or JustSwap system soon!
