@Vertje Without giving away to much info? I can see why you would like to know this.
I am in a unique position where I can buy BTC with local currency and still get close to the true USD value even after fees. Then I also have a solid exchange to sell it. I am not just trading USD and BTC. I have to use a local bank account to trade local currency to USD.
Between all of this there is always a margin of 3-6% per week. Doing max 2 trades per week.
Question 2: Yes, the value of BTCB TC is currently 4000 USD in total. $2000 USD and $2000 BTC
Meaning, the coin will never drop below $2000 as that is the USD holding, which only happens if BTC drops to $0
BUT if BTC raises 10% the coin value will increase to $2200 increasing the total value to $4200 and at that point the shop will increase the prices of BTCB by 10% as that was the growth.
Hope this helps?
