Choose both Bitcoin and some good altcoins. Bitcoin is the leader in the crypto market, it has stood the test of time and a long-term investment pays off. Some altcoins can also make good gains in the short term. At the same time, it is easier to profit with portfolio diversification.
I diversify with coins in My Portfolio, and it is mostly with top coins in the market that has huge market cap. I invested in ETH, and no matter how bad the market gets, I don’t really convert my ethereum to Bitcoin, because I think the both of them are good and is still just going to be the same thing, not much difference. I also have invested in Bitcoin, and majority of my investment goes into Bitcoin.
I always put about 60% of my investment capital in Bitcoin, and thenthe remaining 40% is what goes to altcoins, and about 20% of the capital would go to top altcoins I like, while the remaining 20% would go to any other project that I feel is going to be worth investing, but if I can’t find any good project I just put all of them in Bitcoin and the other top coins.
