The direct purchase feature allows individuals to purchase tokens directly from the person who created them, rather than through a traditional marketplace where tokens are bought from a variety of sellers. This option may be appealing to those who want to support the token creator and have more control over who will receive the funds.
Additionally, even if you are not selling any tokens or the amount that the supporter wants to spend exceeds the value of the tokens, the supporter has the option to make a donation. Using Quick Trade, all funds from supporters will go directly to you.
Overall, the direct purchase allows for direct support from your community and provides an alternative to traditional marketplace transactions.
