Selling bitcoin is just a personal choice.
Hold/sell, different people’s perception of the price of bitcoin
They will buy at a low price and sell at a high price.

Unlike legal currency, no one is obligated to accept bitcoin payments. The value of Bitcoin depends on the confidence of the user. Once people expect its usefulness to fall, Bitcoin will disappear in a flash. Continued price fluctuations and hacking attacks will continue to have a negative impact on the psychology of consumers and investors.

I think it is possible that ETH continues to increase (BTC is limited to 21 million), and the currency price is more stable than BTC. Market value must be stable relative to btc.

I think there are many factors that affect the price of Bitcoin. The government's supervision is one of the reasons, but it will only restrict Bitcoin transactions for a short period of time, so don't panic and keep holding and waiting.

Blockchain technology involves more and more fields. Bitcoin has also been recognized by more and more countries, and more and more people use it as a payment method. Therefore, Bitcoin has very promising prospects in the future. Therefore, it is necessary for university students to step up to the times and learn Bitcoin related knowledge.

I think you can diversify your investment and combine the two proportions into one portfolio. The price of Bitcoin is relatively high, but its credibility is high. With long-term eyes, prices will rise. The price of altcoins is relatively low, and there is ample room for appreciation. However, its security is very poor and may face the situation of the project team running.

Although I really want to invest, I am a student and I don't have a lot of money. So I can only get tokens through some free way, so I will choose to do the bounty.
