it seems that these are the level where prices are not going to dump further downwards.... thanks to hodlers...
True. Its usually the holders that prevent the prices from falling any further. The support levels we see while trading in any crypto currencies in the market at particular points are usually the buy orders that are placed by the new investors. I would say its the new investors that prevent from falling of prices further more, but its also the holders for sure as they hold the coin and dont dump them therefore preventing the support level from breaking. So its said, HODL and everything will be good.
