This post is a typical example of a dubious strategy often promoted in the crypto community:
The essence of the idea: The author suggests buying coins that have dropped by 5-15%, holding them for 24-48 hours, and selling for a profit.
Logical error: A drop in price does not guarantee a rise. The coin may continue to fall or may not recover at all.
Attempt at manipulation: The author claims to "guarantee" profit, but in reality, no one can promise profit in the market.
Promotion of NEO: It is possible that the author has bought NEO himself and is trying to attract others so that the price rises due to demand.
Screenshots: In them, NEO indeed dropped by 16.45%, but the forecasts from the right screenshot are just a marketing lure, not real analysis.
This looks like manipulation, and trusting such "strategies" without your own analysis is risky.
