No one really knows if it is still in progress or it is already over. Just buy bitcoin when you feel like buying. Bitcoin's price today is so low compared to the peak it achieved days ago so buying now would be a wise thing to do. Just hold onto your bitcoin in the long run and you will definitely gain more than you expected. All must be based on your decision and not on other's speculations so that whatever the end result is, no one is to blame.
Yeah you are the only person responsible for your profits or loss and if you find current price good to make an investment then you can buy some coins at this price as we have seen that price has gone much higher in coming days and at a moment this price can be considered to be a good price to buy some bitcoins as we may see 3000 usd price in coming days so even if we at current price then we can expect some good profits in next couple of months.
