The only thing that could beat BlackCoin, imho, is a currency that paid interest based on volume transacted, using some algorithm to determine which transactions were truly long-running investments and rewarding those with a higher long-term interest rate (i.e., you start by earning A% per coin per 8 hours, but after a X amount of time determined by the liquidity of the market you top out at B%, some adjustable rate of interest based on an algorithm that determines how tight the money supply should be; holding coins longer than that, it starts to go back down). In the meantime, having a very low fixed rate of interest effectively allows BC to be a carry trade instrument for Mint and other high-yield coins, should prices stabilize after a couple of years. And whatever happens to the other coins, it can remain so.
A coin with a rate of interest adjusted by the transaction volume is a very nice idea. Maybe, we'll see one eventually. A currency based on the equation of exchange:http://en.wikipedia.org/wiki/Equation_of_exchange
with an interest rate algorithm designed to keep prices (roughly) constant would be very appealing.
)And such system probably can be exploited eg.l fake walls self buying and selling.
1% for me is good as it is.
From point of view in BC you have dynamic intrest every time you want cash out to fiat lol
.2weeks ago you get in fiat eg 0.1$ from POS minig today 0.5$ as you see market regulate itself on their own.
In reality BC have dynamic interest rate:D ^^ just try everyday cash out to fiat and you will see.
