Furthermore, the current price availability is more than anything if you have such an affordable market right now then what else you need.
The price cannot keep on falling forever because the market do not remains down forever. There can be recovery in the market as well. If the demand rises, the price will also rise and there is already a bit of rising trend in it. Now, price is 6540 US dollar which is still low and it is stable between 6k and 7k US dollar which enables you to get it on low price and no one knows nothing about future so you just make a position by investing here.
