Yesterday I bought some bitcoin. I have invested $12,000 in Bitcoin. And in the next two days I will buy some more bitcoins. I wish I could hold these bitcoins. I believe that in 2021 these held bitcoins of mine will make me much happier. Certainly I'm not doing anything wrong by holding bitcoin. As a newbie, I'm not very experienced. So I look forward to the advice of experts.
It depends on your goal but I highly suggest you divide your investments into short/long-term.
With the current bullish run in bitcoin, the prices have been increasing in the past month by 300%. For short-term investments, you can either cash-out some of your bitcoins if it reached its value higher when you purchased it. For long-term, I also suggest that you keep some of your bitcoins as its value may probably increase this 2021.
As someone who purchased bitcoin way back in 2017 (around $5,000/btc), I do suggest to keep at least 80% of your bitcoins for long-term and the remaining 20% for short-term.
