I have think over this event that valentine day will affect bitcoin in a sense that their may be some people who will withdraw their money and they have to use their months wealth in a single day and those who are young they will even sends gifts to their bitcoin users friends in the form of the bitcoin or the Ethereum or may other altcoin for this year the bitcoin value is down but after the mid of the year many businesses will be ready to accept bitcoin so holding of bitcoin will provide monetary benefit.
Well, we can really expect that the Valentine's day would have an effect on the price but I highly doubt that it would be that high. This day, people will need money to celebrate the day with their loved ones but the number won't be that big because most people are being smart nowadays when it comes to spending money. Special days like Valentines make people withdraw money from their accounts but of course, the effect will just be for days and then the bitcoin price will be back to normal.
