To be honest, as you can see, the current price of BTC is just unbelievable, have you ever owned some BTCs before? If so, are they still in your wallet? You may be deadly regretable if you already sold them out? I guess.
If you take a look at the price movement og Bitcoin from the past 11 months up until today you can easily tell that majority of the people who sold their Btc, no matter when, will always regret and Im not exempted. I sold a small portion of my Btc when the price was around 4k. I never thought it could increase instantaneously with a short period of time. I may have regret it but its never too late, Im slowly recovering now.
