i always cash out something at each step of the way when there is a rise. but i never cash out completely. that is how a low risk strategy should be in my opinion.
to tell the truth this rise, specially when it is this fast, is very scary but also missing out on all the possible prices in the future is even scarier.
what i do is that when there is a fast price surge i sell something to get the profit out but i try to do it on the highest price and then when the correction comes i buy back what i have sold.
But i have decided to just hold my bitcoins despite small market dips as we have seen many times bitcoin price falling after reaching new heights and then immediately recovering and reaching ATH.So,i hope that even if price falls,it would not affect the journey of bitcoin price progressing.
