Yea BTC can jump or fall any moment.
I have accommodate few BTC mostly by selling and buying alts.
I want save BTC to better future and have something for retirement in it.
I think that all fiat money sooner or later will land in toilet,
while BTC will grow problems sooner or later will be solved.
You are right, since this thread, bitcoin price too much jumped, even i save my bitcoin and now recently i have sold them, because of highest price of bitcoin, and it really give me superb profit. I never did any hardworking with my bitcoins, i did only hold them, and sold them in a high price, I also suggest don't save bitcoins for a long time, sell them when you think it give you double price.
That's why savings in bitcoin better than any other currency or gold.
While fiat money facing inflation every year but bitcoin keep growing in value.
I've managed to save a little bit btc for future planning, I think BTC3-5 every year is good enough.
you will think to exchange it for a while take a benefit on high price .
to buy again later when the price dropped a little which make you feel like trading , so reinforce your plan to invest for long term then go save bitcoin as many as you can.
just like when the bitcoin price in mid of 2016 around $450 but then in the end of year 2016 increased to $750.
i sell it all , but you know the price keep growing up to $1,100 ! that's why you have to reinforce your plan and hold bitcoin for long term.
