Ok thank you for your help...
so for mining altcoins it is best to setup a GPU miner...
Yes GPU mining is better than any ASICs. For many reasons I had 25 of the Bitmain Antminer S9. And most of them got burnt up even inside the rooms I had them with the room temperature of 20c even before the Return of Investment. After that I am using GPU mining Rigs. There are too many benefits of GPU Rigs instead of the ASICS.
ASICS when the profits are high the manufacturers will build and run in their facilities and since they can repair it does not matter for them the production cost. They are only on sale when the profitability is low. Also the prices are so high that these companies take all the profit you are going to make when they sell the machine.
GPUs on the other hand are available everywhere you can increase the number of GPUs per machine as you earn from the ROI. The initial costs are not so high to take away your profits. All the components of a GPU Rig can be resold or if a single card causes problem you can replace it. Where as in case of ASICS you have to send the machine back and they will charge you the shipping and replacement of parts that becomes too expensive so my advice will be to use GPUs. ASICS are only the wastage of your money. And never get caught in the cloud mining scams. No matter what their sites say and no matter what their testimonials say. They are all paid stuff.
