They will, but not yet. People are coming to make money here. Until their coming rate decrease altcoins are safe to trade.
I know too many people want to buy coins but don't know how to start. Let them wait to buy before we crash the whole market.

yes altcoins will definitely have huge dips when BTC will go for a run. but this year is showing from the beginning that domination role of BTC is decreasing. so we can expect that BTC runs will affect altcoins less with every next time.

most altcoins are still stable and increasing substantially although there were times that they decrease a little bit but they can seem to easily recover in just a matter of short time. most of them had also pump too much like the ones in hawala hat token  but im too unfortunate  and lucky because i didnt manage to hold my coins in a little longer time therfor i only get a small profit and until now i still regret but i cant do nothing at all and that would rather give me a lesson to have a patience and trust on a coin you hold.

overall i altcoins could still possibly  crashed soon because there is no permanent here in crypto and even bitcoin can crash too.

Yes alts will crash. The market is cyclical and goes through the same boom and bust patterns. I explain in more detail in this video: https://youtu.be/w5tm64qqIyg

The Altcoins will fall and rise many more times. This is the usual situation in the market. I even like the fall of the crypto currency because it can be bought at a more attractive price.

That is the point.
Today is a good day to enter into altcoin market.

I think altcoin in cryptocurrency will increase and decrease periodically and it is very reasonable in the world of cryptocurrency. where we should be more careful in analyzing a coin in the future so that when altcoin had an accident we did not get big losses.

Of course, most of the new cryptocurrencies will die very fast, but the cryptomarket have a bright future.
We just need to keep the attention on every movement, just to understand the preliminary signs - they exist - of a coin crash

I think that there will be another bear market for altcoins sooner or later. Im expecting the bull run on alts to continue for the next months and then the bear market will start. I expect it to be kind of the same pattern as it was in 2017 where we saw a huge bull run on alts from march to june and then headed into a bear market.
