Do I need a lot of GPU for trading like mining? And mining and trading is different right. So How will I learn buying a PC? because I only got my laptop here no desktop. Which is the easiest way to earn? Mine or trade?
You are comparing a cherry with a tomato!
Mining has nothing to do with trading, mining with GPU in today's world is impossible and you will need some expensive stuff like ASIC miners or others to mine Bitcoins or different altcoins. Trading coins is a completely different subject and needs charting knowledge as well as basic idea about how to read them through the support and resistance levels and decide when to enter and where to exit. Trading is better compared to mining but is the riskiest way. I saw D3 allowing users to get their ROI in just a month after mining DASH coin so if you managed to get a D3 while roaming around, you must be in profit already atm.
You are right. The Antminer D3 from Bitmain is like the most sorted after ASIC miner for Dash right now due to its efficiency and I cannot even wait to lay my hands on one once the next batch comes out. I recently told someone that over time, mining devices will keep coming out even at very good prices to make the mining industry more of a better place to want to delve into. With Dash mining, and the present difficulty level and as long as Dash doesn't get dashed in value, having my ROI in a very short period, how better can it be?
