None of these coins have the potential of Ethereum, although in general it is a good coin to choose from like Avax, and Polygon.
But for that potential problem every coin is different and will never be the same as Ethereum or the others.

I might also do the same as you because after all these three coins are the top coins of all and there is no doubt for sure,
both Bitcoin, Ethereum and BNB all three are also very viable and suitable for long term investment,
apart from that investment is not an easy thing it takes patience too

I think there has to be a strong reason how we can get in usually we see this kind of coin can only be hyped once. This is dangerous because like who first bought him first who came out buying at the end is the same as throwing your money. I'm not saying your project is a scam, but stay wary of investing in bsc coins.

I hоld almsot 27 altcoin. But I think bnb, cardano has really good potential.

I agree with this observation, Ethernity Cloud has a good project structure and has a very promising product and use cases, and I think its a good choice, but I see one hindrance because it was launched on Ethereum Network we all know that Ethereum gas problem has not yet solved and it becomes worse after Eth price was pump hard. EtherenityCloud team should use multiple chains, Like BSC and Polygon network so that micro and small investors can get onboard on the project.

we need to buy the investment with a reasonable price then only it will be developed and make some little amount of profit otherwise investing on a very low value currency will not always been get success this is my opinion for everyone to get your investment better.

Metaverse trend gives us a lot of return on investment Mana and metraverse projects over the sand and it also provides a lot of benefits in very short timeframe and is also expected to be the same as from other metroverse tokens like ENJ , TLM , BLOCK ,AXS ETC.

wherever there is a risk, it depends on how we manage that risk. investment in bitcoin also has a risk if next year the bitcoin price stagnates !!!
but what we need to understand before investing in altcoins is, firstly to choose a good or potential altcoin and one that has developers and teams who work optimally to make their project a success, secondly we need to see whether the altcoin community continues to grow or decline, I think this is the most important It is important that we pay attention if we want to invest in altcoins.

The Covid 19 health crisis has dealt a heavy blow to the economy around the world. But there are always opportunities in crises. Most of the big companies have grown by turning crises into opportunities.

Whether or not to invest in BNB for the purchase of Kripro will be at your discretion. BNB is a crypto that will always be valued for investment.

If I had to invest such a small amount, I would definitely look for new unknown projects. I would do a good research and fundamental analysis and I would keep my fingers crossed for success.
I think you should pay attention to the Metaverse tokens.

How do you plan on investing in something you don't know about? It's kind of risky. I'll give you a tip I read here on the forum some time ago. Go to CoinMarket, select the 10 first ranked coins and buy 20 dollars of each.

I can’t stop checking RaceFi website every second so I don’t to miss RACEFI listing on Raydium. I lost listing on SolRazr, I lost listing on Enjinstarter, I lost listing on Kucoin, so I can’t fail for the fourth time

The main thing that attracts me to RaceFi is that it’s not just a simple racing game. It’s a whole metaverse, where everything, including gas stations and racetracks, will be owned by users and bring them crypto as income
