I don't like buyback programs, I think that they are an artificial mean to drive up the price, only in the short term (also, only if you burn said coins/tokens)
In this case it is the opposite: the company is using SPHTX to buy the ERC20, so they are actually going to ignite more and more the supply.
Wait what? How? What erc20 token are you talking about, aren't they buying the sphtx tokens from the decent blockchain?
