Can you suggest some precautions for beginners to avoid getting scammed ?
For my suggestion, avoid HYIP and shitcoins then start investing altcoins which has a strong support and has a good repuation so that you'll never get scammed in your investment. Don't look for easy money, everything is not taken for granted thus we should be more strategic if we want to earn more.
Yes this is true. Try to avoid hyip it may be good in our eyes but somehow it can deceive us. They will tell you that you will earn more than you have been invested but the real thing is, they only fool you they only want the referral bonos that they will get once you have been invested some money. Be wise and be a keen observer too.
