I spoke today with a Community Manager from Matchpool (Arnaud Gaboury) and this is what he had to said about the "Refund Option":
"that is in fact a private agreement between one buyer and one seller and this agreement does not involve Matchpool"
Also, according to Ram Avissar (CM)
"AGAIN WE NEVER OFFERED A REFUND, we simply matched a seller with potential buyer"
This is similar to ICONOMI, the team helped investors to trade, but not a refund option. It is just trading.
This is true, ICONOMI did some rebuy, there are some people that missed out of the ICO and are looking to buy token but what they did was to buy the tokens at the average ICO price from the seller and sell it to the buyer. They act as the escrow in the transaction
