most of cryptocurrency are red for now and down in USD terms,, especially bitcoin
at this moment bitcoin price down below 10K USD depends on coinmarketcap data
is this the best time to buy more bitcoin ?
i think now you get the answer from your question,,
because now the price of bitcoin and altcoins is down deeper
i hope you did not buy a lot of bitcoin when the price above 9K USD
maybe the price will go down until 5K USD
