When the scammer tells you...
1) to give him your wallet id and password
2) to use a blockchain wallet he created for you.
3) to fund your wallet after you changed your password
4) that you will get 5000% back in a day (high percentual return in a short period of time)
Any more??? let's discuss!!!!
P.S. by the way, I have found a very good platform called gebepay and I have used it a couple of times and found it pretty useful and safe to buy products or services with my ETH, anyway have a look!
When I see no new ( up date ) or confused information I'll try to find true information and if I can't get it, leave it for good. Actually people have different answer about this but recognize scammer is not easy, they always change strategy after fail ( not like us ). Just always try to find valuable information about scammer, protect our asset and pray. I can't suggest anything else but I believe experience will become the best guide.
