Believe me my friend, anywhere in the world, it is not easy to make money. If you see any airdrop that promises 100$, 200$, 300$, 500$ and above just for referring peeps, or sharing post online, then it is atmost 99% fraudulent.
Likewise, if you see trade signals that promises certainty, or bounties that promises you a fixed price for your token, be wary. It is not that easy nor realistic.
Then why would you spend time on giveaways? I think if you've invested your own money in potential coins then maybe you're already gaining a huge profit by now. It's not that easy especially if you're only relying to free cryptos in online, just gonna waste your time promoting the project but can't get any bounties. There's a lot of ways to earn or gain in cryptocurrency, maybe you're just in a wrong way of earning.
