USDT or LTC for reload. So, LTC is much quicker. Really fast upload within 3 - 4 mins. vs 6 mins. USDT. However, it’s up to you guys to decide what you prefer.
Obviously, do not upload via BTC because it’s not ideal. Only use it for payout. I lost out $10K or so by uploading BTC & it not going in before the cutoff - LOL
