If have to choose the best staking coin, that gives you the most profit for the shortest time, it is 808coin. If you buy 200 million at current price of 0.000004 USD for a total of $800, you can in theory and by chance stake another 80 million in the first month for $320 back in one month.
You will have to know how to download the wallet and setup the config files. Go to their announcement page to find how to do it. You also need a high speed internet access or broadband similar to fios or cable internet. Then you also have to know how to cajole the connections. I mean when it is not connecting or only has one connection, I found it is best to leave it locked and not minting or staking. Wait till you have at least 2 or 3 connections before opening it up to minting. You may have to this after it minted, if goes back to 1 or no connections.
Almost forgot, you also need to put it all together to compound the staking rewards. To do this you have go to the expert mode, send it all together to another wallet. The wallet has to see the whole amount as one piece, to get the most for your coins. So you either send the whole amount as one piece to another wallet, if have sent it in multiple small amounts.
Still, I found it personally the quickest and most profitable staking at this moment.
A big issue here is there is not too many exchanges that trade this coin. It's just Cryptopia, the other exchanges is very low volume. If 808coin can just get into more markets, we may have better prices quicker. I don't think, they are marketing this coin to other exchanges too much. If other exchanges check how it trades frequently, it's a decent coin to have on the low end or macro-coins.
