Chipmixer needs investors as when you mix the coins, you pay the fee and spammers will never invest.
I think you are a bit confused.
Mixing coins is not an investment, but a service you pay for. Nobody invests in chipmixer. People pay for a service (mixing coins)
I was not confused but wrongly used the word "Investment" instead of "fee for using the service" . My Mistake.
Just thinking on which of the two have more funds to invest. Chipmixer source of income is the fee only which they get from their users while cryptotalk has the whole Yobit exchange with them for funding.
