I do prefer bitcoin over other coins because of it's value and I think all can agree, and market cap was never the point here even if other coins have superiority with the market cap the value is more important in every aspect of investing, but I think we can get benefit in bitcoin and we can get more benefit when there are other coins around because we can proceed in earning in a trade.
Benefits in bitcoin are even better other than any coin. This is the first crypto currency and people will rely on it. I don't know even there are some coins that has better feature, many are still depending on bitcoin. An advantage of bitcoin too is that many whales are backing bitcoin. When we see the price increases, many whales are buying some more.
