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.
It does happens from time to time where the percentage of profit is much more higher on altcoins than on Bitcoin, but if you are talking about continous profit and instability then Bitcoin is the best investment, checking all the chart you will see the percentage is much more higher so the best option still is diversification so if Bitcoin cannot deliver at that time other altcoins might deliver the profit.
