You should have taken part in DEEP onion during 2017 and 2018, for a free airdrop token it quickly rose over $1 in value and went on to record an ATH of around $17. If you had sold at the right time you made quite a profit so there are some good opportunities around even with free coins.
Yea, there's no debate that free coins have the ability to make you a considerable amount of money; but if you want to make serious money, wouldn't it be better to study them during ICO and make invement decisions? Hmm on the other hand, most of the participants do not even bother to look into the projects, which I think totally defeats the purpose of airdrops.(Ppl are now looking to just fill out forms and hope to make a quick buck instead of pay attention of what the projects have to offer).
