Personally I don't have any plan to sell my Bitcoin, but it's obviously I will sell it little by little when I see the price is really high. I will not ever sold all of my Bitcoin, I still believe the Bitcoin ATH will never end, which mean we might see Bitcoin will break new ATH for every 4 years.
I will sell my coins is not because I will celebrate the new ATH and enjoy my day, but I will use it to buy Bitcoin during bear market happen.
My plan is to hold Bitcoin till it's been legalized by the Government. Because we maynot be able to buy Bitcoin agin at the low price.
What do you mean about legalized? Bitcoin is mostly accepted in many countries right now as a commodity and now there are 2 countries already accepted as a currency.
