the best way to deal with this is start buying BTC every week, maybe on Mondays? This way you will feel better.....remember, when people are calling for the exact same thing the opposite always happens.
My people always says "Nah who get food to chop they save" (Its who, who have food to eat that will save for investment)
Everyone has he or her own strategy of buying and holding btc, as for me buying btc every there and then is not a best option and 2ndly the fund which we use in buying the btc where are they stock. what if the price go down below what they actually where before your first purchase?.
At my current status unless miracle happens btc is the last coin am thinking of buying currently, because it will make no meaning or add no much value if i buy btc worth 100$ now and when btc hits 25k$ i will only make small or very little % of profit. i preferer accumulating other altcoins like matic than btc
