The above from oldmankid sums up what will happen to EFL if price goes very high.
EFL block times are 2 minutes ave and not 1 minute but still valid argument.
Oldmankid decided to remain silent, but his rubbish still gets quoted I see. Lets try again :
Exposure to multipools is allways a problem because you cannot defend a system against someone who pulls the plug out of it without notice. Difficulty is calculated before work starts. When a big fellow retreats the others will have to solve the problem. Difficulty calculation, whether you call it KGW or Delta has nothing to do with that (hardly).
The decision of a large pool to withdraw mining is based on profit. Mining profitability is based on
1. Total hashrate
2. Average blocktime
3. Blockreward
4. Price of a single currency unit
The vulnerability for sudden change of hashing power depends on the level of loyal hashing power. Currently the NLG-community is willing to pay about five times as much for hashing power as the EFL-community. Mining profitability is about the same through the entire Altcoin ecosystem. I just calculated it for three altcoins :
NLG 0.006 BTC per hour per Ghs
LTC 0.0065 BTC per hour per Ghs
EFL 0.01 BTC per hour per Ghs
This makes EFL exposure to Multipools slightly higher at the moment. We will see what happens with "loyal" hashingpower after september 1st when NLG will reward miners with 1/10th they used to.
