So many people have had the same experience here especially newbies and there are hundreds of such site created with the same intent. They are mostly either casinos or Exchanges
The tricks have been evolving from time to time, but the end game is always the same, that is, send this amount of BTC or ETH to;
- Verify your account
- Unlock your account
- Unlock your rewards
Most of the scam websites using this trick were always updated on
this thread back then
I had encounters with this kind of websites back then but I knew that they were scams because the advertisement is that no money is needed to get the "free log-in reward" but then I completed the necessary forms to put in and voila you need to send this amount to get the full benefits, good thing I grow up knowing about things that are often offered free of charge and that is most of them have an underlying favor that is not worth it to hustle on to get the reward. Hopefully, this kind of trick becomes a normal thing for people that when they see one that does this, they wouldn't even bat an eye or check it out, its tricky thing though as @logfiles have mentioned that some of the offenders are casinos or exchanges, they will lure you in and make you comfortable before they leave you hanging, the only thing that I can think of to prevent this one is to not put a lot of money in the website so as not to prevent a big loss in the case that they did pull a big one on you.
