The Problem with P & D is, that there are 3 ways it could fail
1. Individial or Group buys a coin over the point of supply so it is visible in the chart, but there are no followers to by his dump so the price wents down from where it came.(they make a loss)
2. Individial or Group buys a coin but cant drive price higher, because players which arent visible(flat) on the order table step in and sell off in to the pump. (I use this method sometimes when it is useful, to not show your own intensions&volume)
3. a scammer accumulates before he tells his group, so who come last pays the bill xD
What i read own his site is trading education. Somehow classic "price action" , known from Fiat trading.
P&D is a market manipulation method.
But that must be bad, because it is not limited to a criminal group.
Everybody can do the same since Crypto is to this date not limited by trading rules like the Stockmarket.
I am always sceptical when i hear about a group thing.
As a trader you usually act alone, so your personality is also not towards groups.
Maybe he is just someone who wants to teach people his methods.
Or he gets his earnings by the group fee's and scamming (buying before his group announcements).
I dont know , not my business
