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.
It is a good option of trading but too risky .However when the market behave with you badly you can loose more your funds .I think the strategy helps you luckily but i never did such a trade cause it is likely risky when the both market goes on downtrend you can loose your fund .I think we need to avoid such a kind of strategy cause it will not give you long term profit .
