I won't say "scam". I think you see its movement of going down in value as a factor to consider it a scam; however, it is surely and certainly not the case because of the fact that the market, together with its assets, are just like this. It experiences lows as it experiences highs. So, the better strategy here is to actually check out what should be done during this bad times to actually make it unfold into a good venture in the future. Basically, just turn something trash in something that can be considered a treasure.
