Most people greatly overestimate the potential for short term gains, and underestimate the potential for long term gains.

Many people are excited to think that bitcoin could reach $100k some time during the next year, but if it doesn't, that's not necessarily a bad thing for bitcoin long term. If bitcoin maintains a yearly roi of around 40%, the price of bitcoin will be around $89k in 1 year. It will however be around $1.8 million in 10 years. In order to see these gains, it will be important to stay in the market and hold, because most of the gains will be concentrated in a few spikes that will be hard to time.
