I think this post must be moved in the trading discussion section. Well where do we start, Resistance and Support levels are kinda the basics of Technical Analysis (This is where they based their Buy Low Sell High Technique) However a lot of us fail to identify both of them. Support and Resistance maybe identified as the invisible barriers both protecting and restricting the price action, respectively. Right now if you search "Bitcoin Chart" you will see that Bitcoin is on a major uptrend if you draw an invisible line below the price levels that will be your support line in which you can base your buy points on.
