What do you think will happen tomorrow with the BTC (up or down?) if the stock markets worldwide crash again?
I am afraid that the BTC will then go towards 3k or even less. The altcoins will hit it even harder.
I dont know what i should do today, sell all my altcoins?
Well, no one can tell in which direction the price of Bitcoin can go. Actually I am in shocked when I woke up last Friday dated March 13, 2020 which is the first Friday the 13th of the year waking up that the price of Bitcoin hit very low from $8,000 down to $6,000 in just an overtime span. But I have soon to realize that this might be the effect of the panic of the people because of the Coronavirus that is spreading at a fast rate affecting many people world wide. But instead of coming up into a panic, I remain calm because being into panic will not help the price to rise up once again and can just give me stress.
I don't think that Bitcoin's price can go deeper into its current price which is $5000+ as of the moment down to $3,000 as what you have expected because there are still incoming volume of demands for Bitcoin usage that is resisting for the price not to go down any further.
In the case of Altcoins, if I were you, I will just keep on holding into it and will not make a move to sell it instead I would grab this opportunity to buy more potential and good Altcoins to hold while the price is still cheap and affordable so that when the price goes up once the market have recovered from its great loss after this matter with Coronavirus have been resolved, I will be benefited because I have managed to store good and potential cryptocurrency coins that will bring profit for me. At this point of time, together with keeping ourselves safe and secure from the virus, we must also do not let ourselves feel panic to avoid doing unnecessary things like doing impulsive decisions. Better keep calm and hold all your cryptocurrencies and just hope for the best thing to happen not just for crypto but as well as for the health care of the whole world.
