Waiting does not tent to be a good investment strategy, unless you already have a lot of BTC... Of course, you have likely been accumulating BTC since 2016, so perhaps waiting might work for you, even though it still might not be a great strategy if you have not reached enough BTC and you are still considering ways to accumulate more BTC... which accumulation of bitcoin seems to be your stated goal when you are saying that you are considering selling stuff to be able to buy more bitcoin.
Waiting will only give me regret. Because from my experience while waiting for the bitcoin price to dump, I actually threw away the opportunity to continue adding the amount bitcoin I wanted. While we never know when the lowest price bitcoin and in the end regret will come when we only wait for a cheap price but it turns out that the BTC price goes up again.
Will not waste that opportunity again before bitcoin reaches $ 500k will continue to buy every week and do not care about the price. Because I believe bitcoin will reach $ 500k or even $ 800k in the future.
from the way I am seeing Bitcoin there is no time bitcoin will reduce to a point that people will rush and purchase Bitcoin, because people like to invest on Bitcoin when the price is high and they do expect that immediately the invest on bitcoin when the price is high they will also profit immediately, that has been the problem of people, I want to tell them that whenever you have your capital to invest on Bitcoin don't hesitate to invest because the price of Bitcoin never be constant it will always increase and also decreasees so accumulating a Bitcoin should be in the mind of anyone who is there a bitcoin investor, neither the price is increasing or not try to accumulate your Bitcoin one day you profit from doing that, does nobody knew that the price of Bitcoin only increase and also decrease, let us not be hoping to hold bitcoin when the price is increasing, I think that is wrong investment plan on Bitcoin investment.
