That's where altcoins are useful. When bitcoin's value are so high that giving a tip is such a waste you can use altcoins. Bitcoin is not the only cryptocurrency. And bitcoin will not be on top if there's none on its bottom.
I strongly disagreen Bitcoin is a good cryptocurrency. This has been speedily taking over the market. Its growth and popularity is skyrocketing and this will continue to develop as time pass. Also, a lot of people has been earning good vecause of bitcoin.
