You don't have to enter the Bitcoin market when prices drop, joining now is also a good idea, Bitcoin prices are changing every second of the day. You shouldn't panic when you see the price of Bitcoin decrease because the price increase and decrease is a normal thing.
Whenever the fall price buy bitcoins. I think its the perfect time to buy bitcoins. If you're thinking that bitcoin market is going down and we all lose our money then let me remind you bitcoin is volatile.
