Looking at the top 10 coins, 5 out of 10 are not mineable.
New 3rd generation coins, like Cardano, is showing a trend.
Do you believe this is going to kill mining like we know it?
This is a honest question.
In my opinion, mining as we know it is a fad and will most certainly die eventually. Every day miners are expanding their rigs while others get into the game, this will drive up difficulty and reduce overall profits. Meanwhile, new coins are being created with better technology that don't require mining at all because there is a real impact on the environment via energy consumption and a significant amount of raw materials associated with mining. This cant scale into the future.
What happens next is once mining becomes unprofitable, everyone will start selling of their rigs. The used GPU market will be flooded and NVIDIA/AMD won't be able to sell new graphics cards. Meanwhile, good luck selling your BTC Pro motherboad, risers, and expensive mining frames on ebay because nobody is mining anymore.
My advice: if you are mining strictly for quick profit, get out now, sell all of your hardware and put the money straight into crypto. While its true you can make some nice coin right now, nobody can honestly say how long this trend will last.
Don't get me wrong, I think mining will do well in 2018 but I doubt a 6 card mining rig will be able to do a whole lot in a couple years. Just look at where things were just a few years ago when you could mine bitcoins with your CPU.
At this moment in time, I think if you mine and HODL the right coins, you can make some nice profit in the future. As for myself, I have more than a few thousand invested in mining but I do it primarily because I enjoy computers and building / tuning different rigs, my real investment is in the overall crypto market.
Mine with this in mind
and stay up on whats going on so you can look ahead and know when to get out. The key is to stay ahead of the rush.
