It is true that things will not increase forever, but I want to know when it will decrease? As a lot of people I know everything that can happen in this market, but the current situation is too early to discuss this. I think this is not the time for us to have doubts about it, I think the next time there will be very absolute for this market.
The truth is, you cannot know when it will decrease; and you can only guess not predict so do not look for such hints. Instead focus on your trades, your portfolio and ensure to take profit as oft as it comes. Except you hodling for an unforeseeable future, then your portfolio should be on your mind.
Also since we cannot predict the price the best thing to do is, ask within yourself whether you are able to stay strong when the market goes bearish because it will happen some day. You cannot hope the market will stay bullish all the time.
The smart thing one can do right now is to just flow with the market and make some adjustments like if the price is 45k you can place buy orders for 44k and sell orders for 46k.
By the way guys you can also use platforms like LBC to actually make profit easily because in the local market there are guys who are able to purchase at 5-10% above the market price and there are also sellers who will sell you at market rate and even 5% lower than the market rate for bank transfer or cash deals.
