@neurddom rocking the stage at our #Bitcoin #MASTERCLASS

There are around 12 BTC to sweep from ancient force closed channels from @lnbig_com and ln2me. 1900 nodes that just left sats in ~3k channels. And all they have to do is run a chantools command. Does anyone have a creative idea on how to reach those people to inform them?

Just in case someone needs to hear this: the number of coins you own doesn’t matter. What matters is how much of your savings are protected in Bitcoin. Don’t get fooled by unit bias.

@BitlagerPro @BitBoxSwiss @bisonapp Thats true... buuuut ;-) the implementation if it is specific to them... if they would use a user firendly provider like @21Analytics it would be a charm in UX and userfriendlyness...

@BitBoxSwiss @bisonapp It is not @bisonapp specific but a new EU regulation called "Transfer of Funds Regulation (ToFR)": bisonapp.com/en/blog/transf…

A new low in user friendliniess has been reached. We have received support tickets from @bisonapp customers that were asked to go through ridiculous practices to be allowed to withdraw their Bitcoin. To withdraw their Bitcoin, the user is asked to provide screenshots of the "platform of their receival address that show their name, email address and phone number together with their receival address". Of course the BitBoxApp doesn't have this information, so Bison came up with a brilliant solution: Add multiple accounts and give them account names containing your name, phone number and email! Mind you, this is on top of a previously done 'satoshi test'. This practice is completely unacceptable, ineffective and hostile towards users. We strongly urge @bisonapp to get rid of these completely unnecessary steps and customers to look into using different platforms to buy Bitcoin.

Join me and 70 others next Monday at SHED for the Bitcoin Meetup in Zug.
