I don't think Electroneum will die, it will continue to survive but for the 'hobby' miner with just one rig it's a bit depressing to see that they are paying more to mine than they get in returns so they will move on to some other coin that, at least, they will break even on.
It is depressing for every CPU and GPU miner, not just for hobby miner (like me).
Let's not forget Monero (and then cryptonight coins) purpose was to be easy minable with CPU, besides the privacy thing.
The cryptocurrency is having a bull run right now but the price is not gaining its former price I don't want to say people are losing trust but they are so quiet right now, no news that can get the price to surge, I wonder what those people who predicted that it will go $5, it's a long way for that price.
$ 5 is not a real price, look at the whole market and do not build illusions. Well, if the price is as before.
