I will suggest you to Do your own research. This is not the end of BTC's pump. Still Many new institutions are entering in BTC. So there is a space for more pump. But alt hasn't pumped like BTC. So my suggestion will be keep 50% of your fund in BTC and buy top Alt with rest 50%. In this way you can catch the pump from both side.
Yes, that's a good strategy at the moment, because considering that the next pump on BTC is still very likely to happen this year, it is clear that it is better to keep half of our funds in the top Altcoins, because the effect will always be there if BTC continues to pump well on the market.
Although the market is already overheated, but it still has the potential for growth. Bitcoin has been accumulating its positions in the region of 50-60k $ lately. I think that soon after there will be a break in this lull. If we reach the level of 65-70k $, we can safely speak about the preservation of the trend and the continuation of the bull run.
