I think this is not a good idea for you if this time have to buy bitcoin at a very high price except for trade or investment, for fear the price will experience a decline will certainly lose.
It is not necessary to buy bitcoins if you are very afraid. You can earn coins and save them for the future.
yeah take a risk or go home , hard to expect bitcoin price fall down . it's required strong factor a strong reason that could lead to people divest their bitcoin into cash/real money . where nowadays bitcoin still flying with a lot of good news and positive trends , it's bullish for at least a couple months ahead. however better to do your own analysis, we are here just make a suggestion.
