The ongoing Impact Project (IMPT) presale has now reached the milestone of $1 million raised, barely 72 hours after opening to investors. The blockchain-based carbon credit marketplace had taken the step of launching its sale during a difficult period for the wider cryptocurrency market, yet the market negativity doesn't appear to have blunted investor demand for its native token.

With a hard cap of $10.8 million, IMPT's presale is now almost 10% complete. It's currently in its first stage out of three, with the first offering it at $0.018 and the third at $0.028.

Here's everything interested readers need to know about the altcoin, in case they're wondering whether or not to join the sale.

Beginning on Monday October 3, the Impact Project's presale has already passed a number of significant thresholds, from $250,000 raised in 24 hours to $500,000 within 48. Now, it has just celebrated raising $1 million, with the past 24 hours seeing roughly half a million dollars in IMPT sold.

With each token going for $0.018, this means it has sold nearly 55 million IMPT, out of a hard cap of 600 million. Assuming a similar rate (i.e. roughly $500,000 per day) for the rest of the sale, it could sell out within 20 days.

This would put the end of the sale one Wednesday October 26. Of course, given that it began only three days ago, it could continue accelerating, implying an earlier end.

As for what's exciting investors so much, the Impact Project is developing a decentralized marketplace for carbon credits. Running on Ethereum, its platform will also enable consumers to purchase items with retailers
