If you want to invest in something then all you have to pay attention to is the price of bitcoin you have to keep an eye on all the time. It will always be after knowing the value of a coin, but I think it would be better for you to invest.
Invest folks when you're ready and you have money ready.
Do not invest because someone says so because you might regret it if you're impatient and the price drops all of a sudden. Just as the topic, set a price and aim it until it come.
But if you're not going to tolerate and you seem to be hasty and you can't take it. The market might not be for you so stay just as the majority of being a holder.
