First am not a pro trader, but my trading techniques have proven fundamentals. I recycled around Bitcoin and some handful of good altcoins; I trade with a hand full of funds since altcoins and the bitcoin market move in the opposite direction; I fill my bags with altcoins when the alt markets are down against Bitcoin and sell them when the market is on the rise to buy bitcoin which will be on a downtrend at that moment.
This technique has worked for me over the years.
Mostly if bitcoin pump, altcoins also follow, if bitcoin going down, altcoins as well. So, it's difficult to use your strategy but good for you because you are lucky on using that simple strategy. We have different strategy in trading but always remember that no matter what is our strategy, trading is still risky. We need to learn both the technical and fundamental analysis of trading.
