When does ICO start?
There is no ICO with 421 coin. If you want to get some coins then you can buy them from here
https://cryptohub.online/market/421/ Download the 421 wallet from the OP and then have the coins sent to your wallet for staking. Your coins will take 10 days to mature before they are ready to start staking and depending on how many coins you have will depend on how many coins you will earn. Now is a great time to get in as the price is dirt cheap.
Mining is quite easy too if you have the hardware.
Yes I forgot all about mining 421 lol
Well if people do mine 421 they can have the best of both worlds as they can mine and then stake the coins they have mined for even more coins. I was doing this with another coin and it worked out very well for me as I was earning from both the mining and staking. And right now mining this coin might be a great option as not many know about it just yet.
