For those who advice OP to actually take profit during bullish periods in a cycle, could you truly tell yourself that it has been more profitable for you compared than if you simply had a long term HODL strategy and hold your Bitcoins for more than one cycle? I believe less than 10% of people in BitcoinTalk could claim to be profitable by more than 50% against Bitcoin during every cycle. The rest of us are mere plebs.
Most traders cannot even beat the markets, what this means is that from the small group of traders that can obtain profits by speculating with the price, most of them cannot obtain more money than what they could have obtained by simply holding their assets long term.
That's the actual point. What would be the use of going through the stress, the anxiety, and the mental insanity, if a pleb could only profit less than 10% if he/she denominated his/her capital in Bitcoin? ¯\_(ツ)_/¯
In many situations, plebs like us may profit in fiat, but actually lost units in Bitcoin = he/she is still a loser.
So those thinking about taking profits should be very careful, since if they do so and then the market keeps going up, they could miss the rest of the upward movement, as they could be very reluctant to buy bitcoin for its new and higher price if that happened.
In a bullish market, all DIPs are always for buying. Average your winners through DCA/Buy the DIP.
