The CLOT wallet will not work with BUMBA v2.0. There was a complete conversion from CLOT to BUMBA that went on for like a year. There was also a reduction in total coins so you'd send in 43 CLOT and get 1 BUMBA or something like that. It's been years and I forget the exact numbers. I do know the website to convert things has been gone for years.
You could PM bumbacoin and maybe he'll have a better suggestion.
Oh, I see. It seemed a little bit strange that the name of the coin changed. Will get in touch with him and post an update over here. Many thanks!
Many thanks for your support!
Best regards,
