Right 1 year before exactly around these days I was pretty happy, i was all in fiat and market was almost around 50k or something. But then i somehow decided to step again in the market thinking that it will boom again and basically that was my biggest mistake, since then i have lost almost everything I earned in cryptos due to market falling once again, i just think everyday that how much more could I have earned if I had kept everything in USDT at that time.
At that time you might have been hit by Fomo because when bitcoin will reach a price of $ 50k and above there are many rumors circulating that bitcoin will reach a price of $ 100k. But if you're getting in at around $50k why don't you sell when it hits $60k? maybe you want to get the price more and continue to hold it.
I don't think that's the biggest mistake of entering at $50k, it's just that your buying goals are not clear either long term or short term. If you make a purchase for the long term you certainly have to hold it until now and there will be no loss before you sell it, it's just that the reduction in asset value continues to fall. If you deposit USDT and the price keeps going up and up one more time, then there will be no profit for you. The risk of profit and loss is certain, you only need to do good financial management, and setting aside some money for reserves will help from losses more and more.
