1. Honestly you'll have harder time looking for tester since not everyone have testnet coin. As for myself, i returned few micro tBTC to faucet where i got tBTC after i done experimenting with LN few years ago.
2. Since it's not easy to obtain tBTC in big quantity, you should specify minimum withdraw/deposit amount of your exchange.
If I'm not mistaken, I had about 0.07 tBTC lying around ... I would gladly take part in the testing, but for the next few days I will be busy for obvious reasons. So if any of you are interested, write to me and I will give you a private key from my tBTC
(and you will share with others if you wish).Thanks for the offer, but i'm not sure i have enough free time for take part in the test, so i'll decline your offer.
