Just try to avoid buying the tops and maybe find coins with fundamentals and lots of following and stick with them Also be watching the top 10 coins closely and maybe you will find what you want but truth is every investment is risky Just know what you can afford to lose
If you are still a beginner and don't understand investment fundamentals, try it first. it is never too late and there is still plenty of time to make a profit, don't be too hasty and want to get rich quick, because this is not the place for that. Start with easy investments, like the top 10, because they have a fairly strong value
