In the current situation, it is impossible to say how far this downtrend will continue, that's why it is impossible to keep all investment at one price, we need to divide the money into parts which will help us to buy the coin when it drops again.
This downtrend has so much affected some altcoins to the level of digging their grave, putting them inside and remaining for them to just cover the grave and if care is not taken and we have a quick altcoins season, they will cover the grave and that may be the end to all these altcoins that are not following bitcoin in its rise.
I really pity those who have invested in altcoins during 2018 and this year, majority of the altcoins would never survive this downtrend, and I think investors mind are even beginning to divert from altcoins into bitcoin, and we can see how bitcoin is growing very high now that people are so worried that its dominance may kill the altcoins existence completely. We still have some times anyway, we hope that something could really change for alts.
