many choices, the price is relatively cheaper than bitcoin and the opportunity to make more profit. Maybe there are some benefits if I spend more of my money investing in altcoin and holding it for the long term. But the negative value that I found is that the influence of bitcoin is too big on altcoin until now.

The problem about holding alts for long term is the volatility. you can hold it for centuries waiting for the price to go up but all that waiting and energy you spent could gone in vain just within few hours. i've seen to many alts that slowly and steadily going up and crushed to the ground just within hours or even worse minutes.
