If you have interest in mining don't go for just cloud mining that you can earn just a little and low profit and sometimes that are not legitimate sites you will encounter, keep that in mind. If you really know mining altcoins or bitcoin better have some budgets to buy sime rigs a $5k can start with even minimum from that you can have some equipment to mine cryptos. Make sure that the hash rate when you mine is high so that the profit you'll earn too will be synonymous or even higher than that. I'll recommend mining Monero (XMR).
