I have around 10–15 wallets, each one with about 20–25 USDT. I want to consolidate all of this into one single wallet.
The problem is that network fees increased, and now each transfer costs around 0.6–0.7 USDT, which makes it expensive to move everything individually.
That’s why I’m looking for the best and cheapest way to move all the funds into one digital wallet.
Do you call $0,5 to $0,7 expensive rates for a transaction fee? Ethereum network is the most expensive one compared to other networks supporting USD based coins but I think it's not that expensive to spend $5+ in total to move about $300. This is an obstacle with Ethereum not allowing to send from multiple inputs in the same transaction like with Bitcoin.
I thought about how/why you use this number of wallets and have similar amounts. Did you join a contest or an event with multiple wallets?
About your idea to use a casino. It's your worst option because you still have to pay the same fee rate with each transaction. And you won't be able to withdraw full amount before wagering it at least X1 time.
