Is it better to have 5, 12 or even more coins?

[illetyus]

Option 1 is better.
But first I have to ask you, what is your goal?

1.) BTC
2.) ETH
3.) AVAX

It makes sense to put 3 of the 5 currencies in strong currencies.
But don't you want to try your luck on projects with 100x potential? Chiliz, polygon or shiba no longer have such potential. We are not in 2020.

You can divide your $12,000 into 6 parts.

1.)BTC
2.)ETH
3.)AVAX
4.) An Average Token (Chiliz etc.)
5.) Gem (For example; Curio Cards NFT)
6.) Ultra Gem (For example; Cardstack )

If you can't choose the gems well, you will make up for the loss if you do 2x from projects like BTC and ETH AVAX. If you choose the gems well, you will be rich.

If I'm to select between the two, I'll go for option 2 because it has more assets and with the nature of the market. It would be impossible to accurately predict which projects would give the best return in the future. When it comes to investing in altcoin, diversification is better to spread risk and maximize potential returns.

why choose 2?, I prefer more than 2 and less than 10, maybe 5 is a good answer,
because we know the potential of altcoins which are certainly safe to invest,
I have a choice if you want and maybe you can consider it,1. BNB, 2. CRO, 3. VET, 4. IOTA, 5. IOST.

I like your list better than a lot of the other ones. It pains me to see people are still buying SOL. What do you think of IOTA vs IOST? I only hold IOTA. As to BNB and CRO, I would consider trading one of those for CNDL.

Before answering your question, I need to know what type of invest you wanna do short term or long term?
If you are gonna  for long term , it would be better to not go for alt-coin , select btc for long-term and now it's running in a good dip position.
On the others hand if you wanna trade short term with alt-coin  .Then select the top rows of alt coin without selecting more coins- such as bnb ,Etherium, matic, ltc. 12k isn't a small amount . You can make good profit by doing day trading by reading the candles
