Am I need to answer that, it is common sense " Don't trust anyone here " especially if your conversation is about money.
Its really difficult to give our trust to somebody here in the forum, unless you have escrow that are closed to you or it will depend
on your decision. Or instead of making transaction with the newbie person here in terms of investment much better to use to buy coins in the exchange at least instantly you can do trade immediately once you have the coins you buy in the platform.
In most cases, common sense "don't trust anyone" means not to invest in any project or not to trade with others. Hence reputation is important in this business. Of course, I personally will trust a high ranked member than a newbie. In general, newbies do not care about their accounts, so they can more easily deceive investors or scam traders.
