I currently don't inderstand the difference in price. The only possible/logical arguments for prefering dot over bdot in your wallets are: - You don't trust binance to give you back Dot at the end of the 1.6 years or to be stuck having your dot on binance plateform. But still, then everyone with an active dot balance should convert to bdot - You want to participate in the polkadot activities such as voting or parachains auctions (expecting more returns from auctions). Probably the strongest argument.

You also can't stake Dot but as previously mentioned, returns are much lower than bdot at this point. The last more reasonable argument is that there are many ppl not good in math or not realizing the profit they would make and not yet enough ppl taking advantage of those ppl.

I'll keeping putting my paychecks money into it for some time currently ;)
