The price of bitcoin is already at $ 58k and there is a possibility that this year the price will reach $ 100k so I predict many altcoins will pump the price but not all so time to buy altcoins but make sure it is longterm and big volume and the large impact of bitcoin on altcoins when the price rises.
BTC has great potential to reach 100k, l think it is possible and we will see BTC at this price till the end of this year. But everything is possible, BTC can get also down. If BTC would get down, that means most coins will decrease. That is why most coins' prices depend on the BTC movement. But if you want to invest in any coin, this coin should be the best for the long term such as top altcoins. You should be patient and mostly you will make good money in the next season. That is why none can predict what will happen and bull run can be over in the near future, when a bull run comes, altcoins can not go the moon.
