Bitcoin price might go down in value, but when it comes to crashing down, and vanishing at this moment, I don't see such taking place. Their is nothing lasting forever, but at least things achieve long term success. Bitcoin and other well-known cryptocurrencies gonna experience longevity before any sudden crash down. It's just like Gold, Silver, and any other precious stones, they've been around for many years and still in existence today. Others said such too against those precious stones, bit they're still around till today. Generations of people have passed, still Gold is held in high esteem plus other precious stones. I believe, BTC and any other cryptocurrencies will experience such kind of longevity and never crashes down untimely or all of a sudden without a genuine cause of collapse. I just wish the cryptocurrencies long term success and never yo wake up and hearing the saga that the coins have varnished, never.
