The total market cap may be increase to accommodate small to medium investors but I think 400 million is too much . Maybe max will be 50 million. So that BTS may price around $5 to $8 /bts.
The only way market cap increases is if price rises on existing shares. You can't increase market cap by creating new shares.
Market Cap is the monetary value of all existing shares.
Float is the total number of shares. Or you know, you could just say "total number of shares".
Increasing the Float does not mean Market Cap will increase.
If a stock is worth $100 and you split it, it doesn't mean you just automaticity created 2 shares worth $100 each. You just created 2 shares worth $50 still maintaining the $100 value pre split.
The only thing it mostly like will do, raising the float, is possibly make BTS more liquid. Which in no way means it will be worth more.
