in my opinion if you are going to invest now it's better to choose more in bitcoin, investing in altcoin now has a higher risk of loss, it's better to find safe by investing your capital 70% in bitcoin and 30% in altcoin, if you want invest all your capital in altcoin then choose potential altcoins that are included in the top 10 CMC
What you are saying is clearly a fact, that altcoin is currently in a dilemma and cannot move to escape the difficulties that continue to occur. although many altcoins have started to develop, but they are not comparable to those who do not do transactions anymore. it still remains that bitcoin is still the most reliable investment, although it may be quite a lot of capital compared to investing in altcoin.
