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.
If you are taking about garbage it means it is useless. But some are recyclable. Bitcoin is not a garbage, it is one source of funds for all. I wanted to recommend to somebody that register in bitcoin because it is a big help to all. You can save a money on it. Many people expect too much in bitcoin because it is a good investment at all. Because of bitcoin, they raise the level of their livings.
