1 BTC = $7,992.71 is it now the right time for a person to buy bitcoins and keep to earn more profits OR i still have to hold?
Asking for investment advice from random strangers on the internet is a mistake. You don't know why they are giving you those answers and you don't know if their answers are any good.
In general, if you don't know what to do, then you should avoid investing until you do know what to do. In other words, get out now before you make a big mistake and try again later.
That's true its very risky to depend on the strangers advice on when to buy bitcoin because there is no supporting analysis on that. People can easily tell you to buy but you as an educated investor must make effort to confirm the trend so you cannot lose the money you work for. The best time to buy bitcoin is when you make your own analysis as your basis on your decision.
