Bitcoin price is saying it is true , bitcoin price non stop going down i dont know when it will stop but it is so bad i bough some bitcoings 2 days ego but now price is so bad i have lost my money in 2 days but i will not sell we will see what will happen.
Your post shows that you are young in trading and btc, and you catch wrong time for buying. Its easy, on 750 $ traders sold their coins, after this dump in price they will buy again. After this game they will have more coins. Its hard to catch good moment for buying/selling, cause of that trading is not so easy as it seems on first view.
Anyway after so many months under 400 $, you waited to buy on 700 $, you are not to late, but you will need to wait for some profit. Next time try to play it a bit more smarter! Good luck!
