eXch shutting down sucks big time as i was doing the same thins as you, getting LTC, ETH, USDT and swap it to bitcoin, and they had a free option for the network fees.
now we need to look for a decent alternative and i have not found anything as good yet.
Chainswap.io claims to be no-kyc, has anyone tried it? It has already had a signature campaign here on the forum and on altcoinstalks.
It seems that to exchange BTC for another coin is 0.002 btc which would be around US$189.
chainswap.io looks shady to me, i would not trust them with a single sat.
the fact that the minimum amount for an exchange is so high and them offering sooooooo many coins (like +350), tells me they are not using their own crypto reserves like they claim.
and them claiming to be noncustodial is so funny bacause it's absolutely not true.
But I think to redeem bonus 40x wager is way too much as a starter , keep it to 5/10x and an option to withdraw profit will likely great for user's. It's my opinion as a user's. It will keep hooked as a new user
i agree with you, 40x is indeed hard to clear. but 30x ~ 40x wager is pretty much the standard across almost every casino.
so 10x is never gonna happen unfortunately, after all they are running a business, if they made it a 10x wager, it would basically be like giving away free money.
