I don't know why you all choose to hold risky and unstable currencies, but Coinbase is now offering a non-destructive alternative mining program that can steadily earn 5% per day as long as you have USDT in your wallet and participate in DeFi's mining program. For example, I have 130KUSDT in my wallet right now, and I'm generating 6,000-7,000 usdt of mineral revenue per day from the mine pool. There was no collateral and Coinbase was the first exchange in the world to go public, so I felt my money would be safe. So I choose it. What about you?
Then test that if you think that's good. Don't have the guts to put that kind of amount just to attain a steady good profit. Coinbase is trusted but I'm not feeling well to allow them to hold my money with that kind of amount.
Test for yourself and check the result. Share it here so we can have good insights into your plan.
