i didnt know if i should write this post here or in bitcoin thread
so i have a general idea about difficulty levels
but what i want to know is "how do you decide to mine a coin based ondifficulty"
what is considered a good difficulty for SHA-256 SCRYPT X-11 & all other cryptos ( i have 13.5TH/s bitmain asics)
what are the benchmarks to look at when you are considering mining a coin
do you think solo mining is a good idea ???how do you know the probability of finding a block solo mining?? it is a gamble but it can still make you a ton of more money.
Although difficulty is an important factor when deciding what coin to mine, it is second to many others such as upside, hype, development team and utility.
As for the Antminer S9's you have, just a few days ago a solo miner using 1 S9 found a BTC block. This was of course extremely lucky, but also extremely profitable. The most simple way to get a picture at how long finding a block will take is to utilize any mining calculator and extrapolate the data until it reaches a full block worth of coins. This is essentially how long it will take to solo mine a block. With that being said, those calculations are usually slower than what will happen in reality.
Solo mining if done correctly can be extremely profitable. A large amount of our miners operate in this fashion.
