for me it doesnt matter how high or low the prices might be,the question is if they will invest or enter in btc world can they face the fact that there is a lot of chances that they might lose their money?some of the newbies think that this is an easy profit thing which we all know its not.so i can only advise them to learn first how bitcoin works,research more things about other cryptos aswell.that way they will have a solid idea what really they are going into.and ofcourse they need a very long patience for this.
