Speedcoin is a digital peer to peer open source currency that allows instant payments to anyone in the world. Speedcoin is a light version of bitcoin by working videos and making online transactions easy and efficient.
Please I would like to know the Speedcoin you are actually describing. I did one airdrop sometimes ago when I installed the speedcoin (SPD) app and till date, the coin refused to trade. I have already assumed it to be a scam.
