Bitcoin's all time high price was around $108K, and it's price right now sits at around $82K, this is a fall of around 25%. Judging by all panic that has surrounded the fall, a lot of people have 'bought the top' and are now unsure about what to do next. So let's break it down.
You basically have three options...
1. Sell your Bitcoin. The only time you should be considering this is if Bitcoin has reached your price target or if you're certain it is going to go lower. As a trader you should of already been invalidated as soon as Bitcoin dropped below support, and as an investor you should never have bought Bitcoin unless you were prepared to hold it for at least four years.
2. Hold your Bitcoin. This may not seem like it, but is actually the easiest option, as all you have to do is literally nothing. The hard part of this though is getting away from the charts, it is emotionally tough to watch your net worth decrease.
3. Buy more Bitcoin. The risk of this is obviously that price of Bitcoin could go down further. The upside though is that it decreases your average buy in price and therefore decreases you loss percentage.
There is no one correct answer, everyone's circumstances will be different and therefore people's choice should be different. Which ever option you choose, it is important to think it all through carefully and decide from a place of calm rather than panic, so you don't end up regretting your choice later.
My personal opinion is that Bitcoin is not finished this cyle and will end up making a new high at some point, the price drop is an over reaction in traditional stock markets to the Trump trade wars. Once Trump has achieved whatever it is he is trying to, then calm will return to the markets.
One final thing I will add though, is that this article is completely focused on Bitcoin. Altcoins are a much greater risk and should be treated in a different way entirely.
These are my own opinions and should in no way be considered financial advice.
Always DYOR.
