My question is if it's still worth buying Asic's and start mining BTC in 2018.
If not mine BTC what other coin is it worth to mine nowadays?
until now bitcoin has not run out in the mine and there are still many people who are mining bitcoin.
of course this is still beneficial for those who have expertise and techniques to deal with such as too much electricity costs.
There still people who mine bitcoin but for a newbie, you have to give time to search what is better for mining. Though the price is expensive for hardware, I think it is still profitable. You have to find what is good for mining because sometimes it just waste of your time and electricity.
