Now divide 21M BTC into 1,000,000 SCs. And this SCs will timestamping thier blocks on MC.
that's sounds terrible.
congratulations, you've just succeeded in breaking the first, and probably the last chance we'll ever have at Sound Money, into 1,000,000 Berkshare Buck locations.
Or what do you mean ?
Again
1. There will be few MERGE-MINED SC
2. There maybe tens PUBLIC SC ( you maybe can buy scBTC for FIAT but I doubt somebody will sell you )
3. There will be millions PRIVATE SC ( you cannot buy scBTC b/c you do not know they even exists)
Edit:
There will be thousands LOCAL SC over globe -> you will be not interested in more than few (there where you live)
