Sometimes, when I think about difference between Bitcoin and altcoins, I like to draw parallels to originals car spare parts and alternative spare parts. Alternative parts have different price categories, from low budget to premium, they can have different quality. But no matter what kind of spare parts you use, using original are always better. Even though alternative premium spare parts can "work" longer.
That is a great analogy, and following it I believe that when non-original parts are used they have an effect that can damage the most important parts of the vehicle. In other words, why risk buying altcoins that have a low price that is likely to go down even more and sometimes not go up any more when you can invest in Bitcoin that is totally guaranteed to go up in price and at any price? moment, but I know that it will go up much more than $70k and seeing the history each new ATH is much juicier than the previous one, this should be reason enough to merit the good risk.
