That's right, if I had to choose, I would also choose Binance, especially if we hold the coins that support the launch, it will provide a lot of benefits from the results of the stake that we make, even though it's only 1.9%, it can provide profits.
It is a smart strategy for those who are long term hodlers and do not trade their coins. Other than Bitcoin I think holding coins that have launchpools like BNB or TKO in my country has many benefits. As you said we can keep DCAing BNB and over time the accumulation will increase and the percentage of rewards from the launchpool will also increase. I have been doing this for a few months and it is very good for me who does not do day trading.
