This is an interesting concept, so the price isn't actually decided by the free market and can only increase in small increments? What about if someone were to spam many small buy transactions, would that increase the price multiple times and much more than just 1 large transaction?
The Token price
is decided by the free market
and volume. Token prices get updated after
each P3D token purchase so the case you mention here does not work.
Example: I want to spend 10ETH in this
I send 10 transactions of 1 ETH and pay in total 1 ETH in fee --> 10 * (1 * 0.1) = 10 * 0.1 = 1 ETH
or
I send 1 transaction of 10 ETH and pay in total 1 ETH in fee --> 10 ETH * 0.1 = 1 ETH
The transaction fee remains the same because it's a percentage. Since the token price is calculated after EVERY token purchase/sell both ways net in the same amount of tokens.
