I saw a tweet from someone who invested $500 in BTC when it was at $82,000 and now their investment is worth $3,000! I felt regretful for not investing earlier and wished I had converted my money to BTC.
There are two ways to make profits from bitcoin investment, its either you take some level of risk on trading it when the market is on a particular range and make your prediction on future price, if it works on the same direction you expected then you can make more profits, secondly, while investing on bitcoin at a particular rate, when you hold your asset in your wallet and the market rises as you have mentioned, then you're also going to make more profits.
Now, I'm considering a new strategy: if BTC's price drops a bit, I'll invest the money I have and convert it to BTC. Please share your honest thoughts - is this a good idea or not?
Its a good idea, just invest your money on it, but as you already said, buy the dip and then hold, you will be profitable in that alone, don't trade when you're not experience in doing it.
