Bitcoin towards to $8000, whether the exact reasons why bitcoin prices rise so fast?
What to do now, sell or keep hodling?
You should keep holding now until bitcoin reaches 8000$ for real. Sell it only a portion after 8000$ price has been achieved and hodl the rest. That way you would not have to fell regretful when price goes down and you also won't regret selling early when it goes up more. Anyhow, it would be wiser to diversify your money on many different cryptocurrencies for more profit here in crypto world. Bitcoin is not the only crypto with potential so learn how to pick good coins with potential before doing this.
I agree there was so much coin out there that has a potential however bitcoin is the only currency so far that you could invest for long term ! there was no doubt that bitcoin will hit $8000 maybe this month or next so keep holding your coins.
