Bitcoin has always been the leading currency on the market irrespective of how much a coin may surge. Bitcoin was able to capitalize the market during its early stages before the creation of other coins hence it has got lot of user-base and its community is also strong and supportive which is one of the main factors required for the survival of a coin on the market.
Indeed, even with the drastic changes and events happened in the market Bitcoin still emerged as a high value asset that has gained the trust of many users, investors and traders. I believe, the potential of Bitcoin to survive the market is huge and will always lead as the best currency in the future.
