Sorry but I don't know anything about BTC trading. But want to ask So it seems BTC have risen by almost 450% within a year, is it even possible? Why is that? Is it because of Chinese investors or BTC itself? Also should I receive my payment to BTC or should I just withdraw all my BTC since this is the peak time and it's likely to drop to normal price? Edit. Oh, and is it good idea to have big balance on Coinbase? Should I consider buying hard disk?
