If you are not financial buoyant, I guess buying in the low price is very important to long term investors because it will allow the person to buy plenty of BTC compare buying BTC in the high price when you don't have enough money in your account.
We have nothing to worry about this current price because the bull run has spend long time in the market for investors to earn profit from BTC, and any moment from now, investors will begin to see massive dump that will make them to know that bear market is coming to take place soon. Both long term investors and short term investors use to worry about anything that happen in the market either positive or negative, because if the price dump very well, it will help long term investors to take advantage of the price to buy more of BTC even though you have bought before and you will still like to buy to accumulate your BTC more, and likewise short term investors, they will use that opportunity to increase their BTC in their wallets because is an opportunity for buyers to buy BTC, which they will definitely worry about the movement of the price in the market because every season that happened in the market make both long term investors and short term investors to worry for the next step to take.
The most important thing is if the person has a discretionary Income, then the person can start accumulating bitcoin at any time whether the price is high or low using dca strategy, since it involves regular accumulating of bitcoin. So saying that buying when the l price is low is important to long term investors is wrong because long-term investors are not into bitcoin investment to make quick profits but rather it is traders. More so, a low income earner without discretionary income is not to invest in bitcoin, until he is able to sort out his discretion thats when he should start investing in bitcoin so waiting for bitcoin to dip before you start accumulating bitcoin is a very wrong approach because you will so many market opportunities. As a low coiner or a no coiner should focus more on continously accumulation of bitcoin and don't forget Rome was not built in a day so your portfolio is not something you can build up in one day.
