If you are willing to take risk, then buy bitcoin but if you are not willing then dont buy it.
Rightnow is the best time to buy because its price is droping, but make sure that you have a strong mind, strong hand and strong heart because getting profit will not be so easy.
but many newbie investors do not have a strong mentality. and they are very easily influenced by news that unconfirmed yet.usually this type of investor make other being panic.
So we should guide them about the nature of bitcoin and we should tell them that it is very common to the bitcoin to change the price, most of the time bitcoin price fluctuates and it get high and get down but no need to lose your patience and sell out, with the passage of time bitcoin is getting better now so we should hold with patience no need to panic. If the price of the bitcoin make them stressed then they should buy now and dont keep on checking the price so they will not mistake for the panic selling.
