35k may still be a fair price to join the market,  but also note that,  no one can rightly predicts the price of Bitcoin and how much time you may have to wait for the market to reach your desired profits position,  but then if you are planning a long term holding then you are right to buy into the market at that price,  but if you want to take a short term market position with aim of taking profits anytime soon, you may have to consider the price properly and also measure your risk according to what is available for you and at that point,  you are no longer investing,  but gambling with the price of Bitcoin at that level.

So in such a position,  you must be willing to take whatever reality that comes from your decision since anything can happen and you may not likely be in profit at the end,  but you only lose when you sell your Bitcoin,  otherwise,  you may keep holding until price become more favourable to you to sell.
