i think so risky if you Holding bitcoin a long time , may be just 3-6 Month it's good . but , if you already got cheap or profit you should sell your bitcoin , and waiting dump again .
There are many articles around bitcoin price would reach up to 5k / 10k in longer run. Even we have seen in last few months it has been double. I believe keep it for longer run it will give much more higher return.
I believe it too. Bitcoin has been an amazing pump in August and now still it is going up and up. Now holder will be having so much profit and I suggest to hold it more for a few months. Price charts are going up and so your profit. Just examine continuously the market and just hit when you hold much profit.
