The incentive is too small. Traditional banks are already offering more than that so I'd rather stick to those than hold a coin of a platform that is almost always in hot water It's a great way to advertise their debit card to the masses, and actual way of spending your altcoin in buying real world items however, I don't think people are buying crypto for the purpose of spending anymore but rather safekeeping and investing. Perhaps if they could up the cashback percentage to the smaller holders, it might push them to use the debit card.
I'm not sure where you're from and what kind of incentives credit cards provide there, but 3% cashback isn't that insignificant, it's the most I'm able to get from my credit card and only applies to petrol, and as someone who's regularly using my car, the cashback quickly adds up. It's not necessary to use your cryptocurrency to make purchases through Binance's debit card, you can even use fiat currencies or even stablecoins.
Holding any coin on any exchange is not advised but I believe exchange tokens are exception to this rule.
Why, because the value of exchange coins depends on the existence of exchange itself.
If exchange suddenly disappear, their coins will also lose valu and even your holding them on your own wallet will not cover you from the loss.
By this logic, holding bnb on Binance for getting cashbacks is not a bad idea.
Exactly, if something happens and Binance crashes, then BNB is also doomed no matter where you're storing it. Thus, I don't see why it's a bad idea to hold BNB and take advantage of the debit card if it's useful for yourself.
I see this as some kind of gesture that they are trying hard to make BNB retain its value in the middle of lawsuit.
moreover the fact that the requirements for getting such cashback is to hold BNB and as you said to get the most cashback it wouldn't viable for average BNB holders kinda speaks for itself
the binance very purpose of gaining and increase holders of BNB.
I'd say they are trying to make BNB stronger with all these programs and event coming from binance, but then again the lawsuit involving them should really be of concern first.
The cashback incentives isn't something new, it's an old feature and I remember it from the first day I signed up on Binance, which is quite a few years ago. Thus, your claim about Binance trying to attract investors to hold in their exchange is irrelevant.
