Invest in GPU is still worth??!?!?

If you had start early mining cryptocoins then now are probably in profit. Not even a year now and top 3 cryptocoins are too high.
More and more people are interesting to join the cryptocurrency.

Now the true question is if still worth to invest in GPU mining ring or buy with same amount of money coins and alt coins.
Well if you have already some GPU running and made a profit, even a small, i think its worth buy some more GPUs cause your other GPUs will help you to earn faster the money you invested.
If you are new in cryptocurrency it's not worth of buying GPUs to farm, cause every day more and more people are joining and this make the algorithm even harder to solve as a result you will farm more and more less. The good thing is that if you hold for a while eventually the price will go up cause less coins are produced.

My opinion for new investors that interesting of joining in cryptocurrency is that is better to buy coins,altcoins rather of buying GPUs, yes it's risky both invests but if you do some good research and invest wise with patience you will earn some good money.
