Staking increases the % of total coins held. It doesn mean you will get that amount in profit. If the coins drop in price faster then the % stake then you lose money. You need to time it and not just pick any coin, they brilliant investments I have made thousands of $$$ with staking coins. I have made investing then working. say 55% from investing the rest working.
staking has nothing to do with investment and there is no "company" involved. if there is any company that is promising you 150% return and calling it a "stake" then run away without looking back, they are trying to scam you.
i am not going to click that link you posted since it seems shady but i assume that is the case here.
staking is the process of you first buying some shitcoin, then installing its wallet (full node), let it sync and then leave it running. you get paid based on your total amount of balance and how much you contribute to the network by processing transactions. which will cost both computing power and network.
Ya shit coin that has paid back 10 fold. Definitely shit.
I was told many times by idiots who know nothing that this and that is a shitcoin. I smile and laugh as I cash out. ^^
