I think we'll just have to agree to disagree on the BlockCard transactions. I can tell you that I have spent many hours mapping out the transaction history of all the active Ternio wallets, including the BlockCard wallets, as part of my due diligence. This is not hard to do, but it IS time consuming. I believe I have a good understanding of how the process works and have used my knowledge to find opportune times to buy additional TERN since there is a manual (with a time delay) part to the process.
If you spend the time to do your own research, you will find all the answers you're looking for.
If you have done your research and feel comfortable that it's correct, I'm more than happy to know how this is happening. As far as my understanding and research goes, I'm not seeing any buy happening on any exchange. Yes it's time consuming and it becomes even more difficult since there's no data provided by the team on how many btc/eth/xlm has been deposited so far. I have tried to track around 40-50 new wallets created after blockcard launch and noted the time of there Tern deposit and matching it with buy happened at that time on stellar decentralized exchange, but not found any link between them.
Why team don't want to clear air surrounding this question? Why are they always saying it's magic, we won't disclose any detail on it? What's there to hide?
And then banning those who are asking these questions again as they're not answering that. It's going like this, you can ask question once and they'll answer with we won't disclose it, if you ask again you'll get a ban.
