The Proof of Stake Pools website has valued Stackbit at 1/2 sat each. The current market on CoinExchange is well below this. You can use Stackbit as a form of payment thru several discords to purchase newly listed coins and coins that are in pre-launch.
The newest offering gives anyone an opportunity to purchase 247coins, that are soon to be launched. This coin will have a fluctuating staking rate between 7% and 2400%, scheduled over the first 2 1/2 years of staking. However, coins purchased in the pre-launch phase will multiply at a rate of 1000% per year until the official launch. The program is being offered thru the 247coin's discord
https://discord.gg/6FDqGZy and in cooperation with the Proof of Stake Pools website.
This is unique because it allows you to purchase 247coins with BTC or SBIT. The advantage of buying 247coins with SBIT is that you are able to buy twice as many 247coins with SBIT than BTC since you are able to buy SBIT for far less than 1/2 a satoshi, on CoinExchange thru the Doge market there.
You are also able to purchase POSP tokens thru the Proof of Stake Pools discord
https://discord.gg/fDBjUdA with Stackbit. The exchange value for Stackbit is also 1/2 satoshi as well. This means you are able to buy the tokens thru their presale program for half the cost of buying them with BTC.
Stackbit(SBIT) are slowly being used as a form pf payment for many things, and hopefully in time, there will be many other things that you can acquire with Stackbits. The ability to buy twice as much with Stackbit is a good reason to use Stackbit for purchases rather than BTC.
