To realise quick profit in Bitcoin, one can be so lucky to buy today and the next day the price rise giving unimaginable profits. The reverse can also be the case and the result could be a huge loss. In reality, this is pure gambling which can be avoided by simply adopting the long term perspective.
Quick profits in Bitcoin sound to be almost an impossible thing to achieve for small bitcoin investors, majority of those who benefits from Bitcoin price sudden increase are thise who buy a whole bags, those are the whales whi can buy Bitcoin i several units, sime time like 4 Bitcoins or above, that way, whatever the percentage of the price increase, you definitely have good amount as profits turn out.
I still feel that long term approach gives bigger profits in addition to less stress Those who bought Bitcoin early part of the year and refused to sell might have seen good profits now far more than those who sold when the bull run started. Those they will hold into next year following the halving might even see more.
Long term approach is the best for mostly small Bitcoin investors those that buy small amounts of sats and hold for a long before selling and at the same time accumulate more Bitcoin while making good use of the DCA tools to gain long-term benefits.
Even for myself, I don't target quick profits in the investments I have made because I put in an amount that may be small enough for them but not too small for me. Maybe that's the example where I target investment in the long term so a small increase will not see a profit in my portfolio but at some point in the future I think I will see a larger percentage in profit and that may be decades in the future.
It's quite right as you say because if big investors can buy 2 BTC or 5 BTC at once then they will see quite a profit if the BTC increase is above 5%>. Even if we bought $10 in Bitcoin when the price was $15k and now it is $42k then we have seen quite a significant profit in our investment but that is according to the capital we put down. For the long term, it may not be possible to calculate the increase in the short term because the target could be an investment made for in the next 10 years.
