People who panic are not investors but they are traders.
People who are slow and full of hope are not loyal or long term investors but they are traders.
These two characteristics can be ignored in each of you.
Just buy BTC and save it until you have children and grandchildren because Bitcoin investment is very good for the long term.
I prefer the old style of investors who accumulate bitcoins gradually but they don't sell them at every recorded ATH. why don't they sell because they know bitcoin is very limited. Whatever happens, buy bitcoin even if it's $10, do it gradually.
Do you know that bitcoin investment is risk, what I will tell you is that don't bag your eggs with one bag, you can invest in bitcoin for long-term but is not something that you will invest for your future children because its clear that nobody knows if the technology of bitcoin blockchain will fade off one day, their is a place I read in this forum, it stated that you should make bitcoin your side hustle, so as your investing in cryptocurrency you have to be mindful and don't put all you hope on it, now bitcoin is increasing and everyone is ready and interested to buy more bitcoin, but never know that bitcoin price can crash from this high price to low price, and it has happened in this form so many times, and it's possible another currency that is higher that bitcoin can be introduced.
It seems you are confusing your self here there is no different between long term and future so saying that Bitcoin is not we should invest for our children in future can be wrong one thing you should know about Bitcoin is that Bitcoin has been tested and trusted so I don't think it is something that will fade up as you have said for Bitcoin is not like other coins like shitcoins for Bitcoin has great potentials in it that has made investors to always invest in it for a long time purpose.
And also when mentioning the word cryptocurrency you should try and be specific so that some one reading will know the exact coin you are talking about because the word cryptocurrency comprises of many coin so if it Bitcoin you specify it, if it is also shitcoins you specify it so you won't get some newbies or new investors here confused.
One thing you should also know is that Bitcoin has come to stay.
