I have to answer everyone for correctness. I confirm that it was copied from investopedia (but we had written it which was the source). we didn't think we would unleash so much negative aggression towards us. Maybe it was my mistake, but I thought that explaining something that others had already done well, would not have been harm. And instead I understand that we have been judged and even put on the SCAM lists. I'm sorry but not, not this, not now, where the social intent does not deserve this ...
