I am looking forward to hear your opinion. In case (and this is my expectation) BTC goes up first, it might be wise to allocate your funds in this way!
Yes, this is the general trend as on date we are seeing. Since bitcoin is the most popular crypto currency and most of the people coming in the crypto market, start with bitcoin only, we are seeing the impact on the bitcoin price first. However, while allocation of your investment, it is not wise to buy only one asset in any way. Always try to buy three or more assets just to stay on a safer side. If bitcoin price goes down, you will at least find some support from the other coins you are holding here.
