I am totally being honest here: me and a friend were looking to jeopardize some of our savings and purchasing the KNCMiner Jupiter (2nd generation - the one that is still not ready for consumers but can be pre-ordered).
On the surface, it looks good. The one thing I can't figure out is - is it still going to be a good miner once the difficulty will adjust to it?
Many will get there Jupiters before me, and they are all going to put them to hard work. Once this happnes, how am I to know the effects on the difficulty? Perhaps by then the Jupiter will become just like another 6990 (of the time)?
Thanks a million for your help and advice!
Learn from others. Pre-ordering is a huge risk. You don't know (a) when it will be delivered (b) the global hashrate, and (c) the bitcoin price
If you like huge risks, go ahead and pre-order. These companies love taking your money
