I believe that every good lesson starts with a good story and on this note, I want to tell you about the experience I had that made me cautious of "Get rich quick" schemes online especially those pertaining to Cryptocurrencies.
I discovered Bitcoin in early 2013 and although I didn't take it seriously at first, I was earning little money from it doing tasks online (pay for view, faucets and such), I took it more as a hobby and never intended on selling the bitcoin, I just knew in my heart that it would do great so I wanted to accumulate as much as possible without having to spend my money buying it (this was before I got into mining), fast forward to 2015 when the money doubling schemes were everywhere, I kept seeing adverts online and even though I knew better, I decided to invest in one of them (Avabitcoin) with the coins I got from my early days of discovering bitcoin, Avabitcoin was a platform where you invest bitcoin and they supposedly invest it and return profits to you on a daily basis, I decided to take the risk and invested for the first day, got back my money plus 12% profit, and greed overtook me and I did kept doing it for 2 more weeks before they vanished with my funds. I kept going all in even when I had already doubled my money.
If you want to avoid getting scammed online, you just have to follow the following:Greed: Greed has led a lot of people straight to rekt, like my story above would have told you, I couldn't resist the pull of greed even when I had doubled my funds.
HYIPs: When it looks too good to be true, then it's probably too good to be true, when you see any investments that promise high yield returns, please stay far away from them, when you see genuine projects that offers returns, most of their returns are so low, some of them are average of 10% per annum and it's a wonder that we see platforms offering 10% and above in a day and we gladly jump straight into rekt, like I said, if it sounds too good to be true, then it's too good to be true.
FOMO: If not for the hype that Avabitcoin generated, I would not have invested in it in 2015, learn how to DYOR and avoid what others have to say about projects they seem to support, infact your mindset should be that everybody is trying to rip you off so if you always look at every hyped project with that mindset, you would have a clearer picture of the project without the blindfold of FOMO.
Rushing: Avoid rushing into any investment because you heard it's paying others, one of the virtues of a Cryptocurrency investor is patience, Cryptocurrency investments are high risk investments and you have to treat it like gambling, never invest more than you can afford to lose, never go all in on any project no matter how good it looks.
EDIT:Click on random websites: Many airdrop websites you see these days asking for personal details are fake and many of them are just clever ways to steal your private details and use it to steal your funds, be careful of the links you click and if possible, bookmark your sensitive websites (the ones that need private information like private keys and passwords) so that you wouldn't fall for a clone website.
Use new wallets: We can all remember the recent incident that happened with satowallet where the wallet stopped working and users lost a sizable amount of funds, we should stick to the existing and trusted wallets instead of just jumping into any random wallets swe see online, many of them don't have your best interest at heart.
Repeat Passwords: I was just surfing through the forum a few minutes ago and saw a post where a guy managed to hack an ICO website and contacted the admins and the admins just don't care, never repeat passwords in two websites so that if a hacker manages to get their hands on one of your passwords, they would not be able to affect your funds in other platforms.
Please try to include telegram scams on your list, they are trending big now and almost all newbies from india have fall victim to this scam tricks, scammers steal project teams image and use a near identity name too, for example a legit project team member can go by @fisher as the username and scammers will change the name to @flsher with same profile image to give you good offer, if you don't check very well you will think its legit.
If you have any similar experience, please kindly share it, it might help others (especially the newbies to avoid being scammed by shady projects out there and if I see good suggestions, I would edit this post and add them as well.Seen some awesome answers and I would be adding them soon, keep the suggestions coming.
