I see every day bitvoin becomes more expensive. I understand that this is a very good investment object. That's why I buy Bitcoin. In the future date of my investment will bring me profits
The Bitcoin exchange rates are extremely volatile. The exchange rate was $1,200+ per coin in December 2013. In 2014, it was mostly in the $500-$600 range. Then after a few months, it nosedived to $230-$250. During the last 6-7 months, the exchange rates have appreciated by around 200%. But I am not sure whether the momentum can be maintained in the future.
Let's suppose that you're one of the unlucky ones that chased the market and bought at $1200 per coin. It's pretty obvious that if you sell right now, you're going to lose money. I think even though the price of bitcoin decreases a lot sometimes, you just have to wait longer and wait for the price of it to pick up again.
Those people that invested at $1200 per coin most probably already did panic selling but I guess there are also some of them that are still waiting for the price of bitcoin to go more than $1200 each to get profit. After all, it's about holding your coins for a long time. If you don't wait for a long time, you'll either lose money or just get very small profit.
The most effective way to earn here is to hold your bitcoin, the more you hold it the more in increases it's value but that's not easy as like you said the price may go down and that think that it's normal in the crypto world but as long as you believe bitcoin will rise you are fit to hold.
