I spent 50% of my salary buying BTC each month and I have saved some BTCs. I will keep buying BTCs till the BTC price is too high for me.
It is nice of you to make such a big effort but there are moments to buy and moments to sell right now the price of bitcoin seems to be very high, at least to me so may be it is a good moment to wait for a price decrease so you can buy more with your bitcoin.
Yes, There is always time for sell off and buy ins. As what you said, this time the price is seem so high and it is a great option to unload some of your bitcoins and sell it for fiat then just wait for the price to dump and buy again which you will have bigger amount because you will buy it on a cheaper price rather than now. That is trading and that is awesome thing to do.
