No matter how promising a project might look, especially if they are new projects just look them as if they have nothing to offer and invest only what you can afford to lose. Do not keep your eggs in one basket, do you fall in love with a single coin, no matter how good they are always keep digging, many more good gems won't hurt than relying on a single gem 💍. Be smart
No gems could be found anymore,it could be a metal same like which is already existing with us so risking the money is not worth on new project anymore unless that project got real hype and can be able to make some quick bucks by dumping when it hits exchanges.
As much as possible let's just use the fund we are earning from campaigns and use it in trading or investment if we really wanted to take risk and not our hard earned money. As risking your savings is for me not advisable enough as crypto investment is risky at all, wherein you don't know when are you going to get ROI, or worst you will lose all your investment.
