The Fee is about 10%, that is not real.
Other possibilities to buy with FIAT?
Would it work out better to buy ETH/BTC wait for growth and then use the extra funds you have raised to buy some FSBT.
This means instead of spending 10% on fees you can maybe use an extra 10% to purchase funds (obviously this all depends on the performance of ETH/BTC).
If I understood it correctly, you mean to buy ETH or BTC now and then wait for it to go up and give some return then buy FSBT?
But in that case FSBT is currently offering some bonus also which may not be available in future.
I think he means instead of buying FSBT now with Credit Card and lose 10% commission charge he would get ETH/BTC now since it is low and wait for it to go up; then he will be selling and buying FSBT; he will end up buying more FSBT with the same original investment given ETH/BTC went up; the profit he made would add to the original investment to get more FSBT.
