it should be noted long term we would like to se a strong support above 40k first before any sustainable rally can occur as this may just be a holiday run up only to repeat the cycle of falling to previous ath (even lower, tho doubtful if supply drys up in exchanges) before the halving it would be prudent for the wise trader to DCA anytime we approach 20kish imho. certainly would be working for you had one jumped on btc as it fell under 20k for some weeks no matter what price you would've paid you would be up a minimum of 80%. so zoom out, look at the cycles, and play the trend whatever direction it goes in grow your position in BTC and take profits for the bloody discount days on the occasional alt coin for a diversified portfolio. these are some of the best times to be researching who is going to be around next bull run after the halving, with many still 80% off their all time high.
