Depending on your asset type and the strategy you may have different plans for yourself if you are just talking about bitcoin in my own idea holding bitcoin on your own wallet is the best idea to get benefit and keep your asset safe from and risk but still there can be some options and these are not recommended at all, for example, you can hold your bitcoins in some exchanges where they offer some investment plans how it's not safe at all and even if you use famous and safe exchanges your funds are still in danger and the option can be putting your bitcoins for collateral and take a loan to work with the money and earn more, all these methods are dangerous and if you check the bitcoin in long term you can see the best option is to holing for the long term in your own wallet.
I have the same opinion. Giving someone your bitcoins to gain an "even little" annual interest rate is risky and
dangerous, because at present the cryptocurrency world is full of fraudsters. The golden rule is "
Trust no one". Even here, on the Bitcointalk forum, some people take loans in BTC, and then they run away with stolen coins. Of course, the profiles of such users immediately receive negative feedback and a scammer flag. In any case, lenders suffer damage.
In general, I agree that
HODL is the best financial strategy. However, I am
not against investment plans offered by BlockFi, Binance and other large platforms with a perfect reputation. I think that at least 50% of your funds should be in your cold wallet. You can lend the rest of BTC coins for credible legal entities or trade them in cryptocurrency exchanges.
