Good to know you have some points. That means the airdrop is been legit. As for the exchange, yes they're good and very secured. I have talked about them couple of times but you can still try using the older wallet you think you're ok with and see for yourself.
Well Im not confident importing my active wallet there which has a good number of initial bwb tokens. Yeah even though theres a lot of feedback from others, I might wanna do the background checkbmyself for the exchange. I am not saying their not legit but a thorough review, scrutiny, or checking is always a must. Once we import our wallet its like laying down your foot on the ground. Better safe than sorry.
