@CryptoLily Hi, just want to ask about the part on trading.

On ViteX website, the mining dashboard tells you the real-time expected mining cost . If cost of mining a VX is lower, start trading. This is why its better to hold different assets. If market price is lower, you are probably better off just buying it from the market.

I can't fully understand this part, this is the only part that I can't understand.
1.) What is the mining cost?
2.) And when you said 'If cost of mining a VX is lower, start trading. This is why its better to hold different assets. If market price is lower, you are probably better off just buying it from the market.' Isn't trading and buying it from the market the same?
