For some coins, maybe yes but the minimum amount to be able to stake is the only part I can't really afford. However, If have enough money, I will buy altcoin to stake and get a profit from it.
I would not risk it because I have no luck in gambling. It's like a game of roulette, lucky or unlucky.
I dont think it's like a gamble, If you are going to mine PoW coins, you'll need to buy rig and manage it (pay electricity, maintain the equipments, etc), but PoS coins is more simple and is basically cheaper than buying rig. For both you just need to choose the right coins so that in the end you won't get loss.
