People are more pose to trading bitcoin than altcoins because of many bad experience about altcoins. Recently many traders got a bitter pill of altcoins after they failed to perform like we saw the bitcoin did, so many are careful to stay close to bitcoin in other not to miss out of gain.
The numerous number of altcoins on the market makes it very difficult to choose which altcoin will perform at a particular period of time. This is actually the bane of most of the amateur investors because they cannot perform the thorough market research to identify the potentially good coins. Even with the experts, sometimes things don't always go as yielded from their researches. However, amidst this level of risk, it is always imperative to do the research because it reduces the level of risk of investing or trading with sh*t coins.
I think that the cryptocurrency market in the future will be able to hold 5000 Altcoins without any difficulties. At the same time, the liquidity of Bitcoin and Ethereum will only grow. Now is a good opportunity to buy Altcoins at super prices.
