I will just sell today and hoping that I have fiat to buy again tomorrow, but procrastination will play in, and I will forget about buying and eventually the price will abnormally rise and I will miss out the opportunity. If you look back the wallets you have used in the past, you will regret how you spent your BTC in the past.
I suggest that you set the prices you want to buy or sell in a few moments before you want to buy. I usually stick with what I have set for myself and I rarely don’t change it no matter how crazy the market becomes.
I don’t think of ‘what if’ questions like what if what I had invested in was not enough or maybe it’ll rise more. Just go buy at your own pace and everything shall follow.
