Mining is more of a low risk long term reward project, its usually better to just buy the coin directly if you believe in it and want quicker profits.
But investing in crypto also carrys the risk of all your investment being virtual, while mining atleast secures part of your investment in hardware which has some resale value.
I know someone who bought AMD cards and setup their own mining rigs,it cost around 4,00,000 for them and they used to mine altcoins on it but with the current price it is no more profitable they considering sale the equipments and want the money to invest back on the altcoins rather than mining it.
Mining can be profitable at long term.
Well thats a pretty steep price, I think he purchased the parts during the mining peak when everything was double the price, and even then he got scammed with the prices.
Mining hardware has been really cheap this year with the crash that happened last year, and prices are yet to rise again even though the bull run has begun.
There are a ton of great resources in the altcoin mining threads on bitcointalk, spend some time reading those, theyll help.
