at 20k? you would buy Bitcoin than mining this? or because you only have small funds and just buying small part for at least having bitcoin in your wallet?
I support yours because mining nowadays is indeed having a little chance of earning than buying the coin and keeping it on your wallets.
I think more profitable with buying bitcoin although with small fund and keep holding in wallet without need to pay electricity than used small fund to buy mining tools, actually small fund just get low budget for buying mining tools except need to pay monthly electricity. But and invested with bitcoin although small fund we don't worry about payment bill electricity every month, I think need bigger fund support for mining depending several items with mining tools have expensive price. Investing in bitcoin we can sell anytime we want if bitcoin reaching higher price and seems faster to get back our capital than used to buy mining tools.
Buying is more suitable than mining if you have the necessary funds. Because if the price of Bitcoin falls further, then mining has has to face more losses. On the other hand, money spent on various equipment can also be another cause of loss. Considering the current time I think buying is better than mining.
