It is true the Bitcoin can crash at anytime. It is better to rely on other currencies as well like the alts. I have a few buddies that at the age of 17, engaged in bitcoin and trading in Binance and Bittrex: they were able to pick up a few bucks even as a student. These cryptocurrencies are for everyone, it just takes a few minutes of your time to study and learn the market in order for you to get some profit out of it.
