I am more lean toward surfer play by feel, but this is not something good based on my experience this way is only suitable when the market is bullish, why? because surfer needs waves and waves describes something that goes up and down, meaning when there is a decrease there will definitely be an increase and so on, buy when down sell when rise. but this is will hurt you soon or later, sometime must be chess master.
On a downtrend you'd want to short the coin and re-buy when price stabilizes at a lower price... Get it right and you will have multiplied your assets...
It seems that this is what cryptocurrency trading is about.. And basically trading everything.. Buy low, sell high. Unfortunately, this market has a low market cap and whales can still manipulate it, which is why this game is not only very difficult, but small fish are practically doomed to lose.
