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.
I agree, first no one will be able to predict the future. Also each person have different read on their charts, as well as they have different strategy and profit margin. If I were you since it seems you do not know how to read charts just buy some Bitcoin then just hold it for a long time.
