PPT Tokens are nor crucial or an afterthought.

Even if you are a Fiat Investor, Populous Business will be happening by Smart Contracts on the Ethereum blockchain. If you deposit $50 USD fiat to the Populous Platform, it will be converted to Pokens (a token, (not PPT)) before you can invest in invoices. Populous will charge a 0.8%(?) conversion fee.

If you deposit PPT to the Populous Platform, it needs to be converted to Pokens before you can invest in invoices, but conversion fee is 0%

Using PPT also has other advantages over fiat:
PPT investors have 'First Bidding Preference' bidding on high yield invoices. Fiat investos have Secondary Bidding preference.
PPT investors can bid on 30 Day, 60 Day and 90 Day terms. Fiat investors 60 and 90 days only.
Fiat investors will be unable to invest in high yield invoice terms (max 6%). PPT investors max 10%.
PPT will convert to any Poken. Fiat is limited to £ GBP and ¥ Yuan Pokens (British and Chinese Invoices).
No KYC needed for PPT investors. Fiat investors has KYC requirements.
PPT investors can create bidding groups. Fiat investors can't.
