Now implementing this strategy is the most ok, because the current BTC prices are very low and can fall deep, so buy them now do not miss the opportunity.
I always believe that bitcoin still promises greater profits than altcoins. When the altcoin owner sells it to play to bitcoin, I agree. But having altcoins is also okay, because besides the price is cheaper so it doesn't drain capital, the benefits of altcoin trading are also good. For better investment, it remains bitcoin, because based on statistics, the longer the price of bitcoin is more expensive, meaning that the profit is greater.
bitcoin is downtrend, it's better to play quantity in the altcoin first, at least keep buying bitcoin but not for scalping, these two coins are good, but traders also have to have a strategy, I only sell the altcoin profits that are converted to btc, but the fixed capital that I use for buy altcoins that have better potential now.
