mentality is needed in investment because every investment has risks. but you can minimize the risk by buying coins that are already strong on the market because by buying coins like ETH or Bitcoin I think you just need to be patient because these two coins are very good prospects in the future. but if you dare to speculate, I think buying cheap coins can be very profitable quickly if you can analyze it correctly.
