I personally believe that the train has almost left the station, which is why I am wondering if it makes no sense to dollar cost average at this time.
We are already reached over 300% of previous all time high so in this case you are right, investing all your capital is not really a good choice for long term investment but if you are looking for short term profits then you should invest right now because we can see clear bump after every correction but we also has the risk of entering into bear market in any time.
