Yes I think if you invest in Bitcoin when its price will increase then it is good for you. This is the only opportunity for long term investment. I think Bitcoin is the only safe currency, if you invest in this currency then you can make your future bright. There are many who want to buy it when the price is high but they may not know that if you buy it when its price is low then you can earn much more profit from it in the future.
Getting yourself worked up trying to outsmart the market is useless because Bitcoin is still very cheap at this present price if compared to how much it might get to in the future, so waiting for a dip or trying to buy in a favourable term as you think is another way to waste valuable time and buying opportunities, so as long as you are thinking long term, just buy once your discretionary income is available, in the future you will be happy with yourself that you made the right decision now that the opportunity is still available.
Perhaps bitcoin market is not like the stock market that closes during the weekend and opens on days of the week however, the most encouraging discussion or discipline is that one having the capacity or capital to buy or invest whatsoever amount and it's confused with the current price of bitcoin in fiat or dollar is quite unlikely to achieve the same bitcoin in the nearest bear market, you might be able to have that amount later on yet if bought today at the current price could still find it possible to buy and additional bitcoin during the bear market. Then it becomes a double win or buying at cheaper or better position.
