Well, you know, buying cryptocurrencies on their high is a thankless job. These swings of BTC between 30-33 thousands are rather good for short-term trading, but long-term investments are better to make when everything totally dumped.
The price swings still kinda scary though, it's indeed suitable for short-term trading but the price could just go fall down at anytime if the price fall break past $30K point.
Im no expert but I think buying BTC at this price is still a good one, on the future we can expect that BTC price will go to 6 digits already and that we wont be able to afford it that much already, BTC is having its new ATH at the moment so just wait for its correction before buying.. This price is good for swing trades only as you know BTC price flactuates this days too fast.
Look at this price of BTC tho, really do fluctuates really fast so its good for swing trades and not hodling as history may repeat itself again where BTC price pops and hodlers who bought at its ATH before suffer from lose. But I actually dont think that you will be much affected if you are a hodler of it as you can have patience for years until it had its new ATH again.
Definitely, buying after correction is good enough but there's no harm in trying to buy when it's at lowest point. Though I doubt that the price could go any lower than $30K in the upcoming weeks but if the news regarding bitcoin adoption keeps appearing on many medias it's fair to say that maybe the bull run is not over yet.
