many choose Polkadot, I also choose polkadot to be recommended, but don't let you not choose Tezoz too,
if you don't buy Tezoz to have on your portfolio list then that is a big mistake!, remember Tezoz has partnered with a successful football club,
yeah manchester united!, so buy the XTZ for the long term, I'm sure the XTZ will cost more than $10.
I would suggest you to add. cosmos, Luna and Polkadot because all of them are going to perform extremely well once Bitcoin is stabilized above 50K. Luna and Cosmos network is attracting huge investment and protocol on their network are giving huge rewards who stake and provide liquidity on their platforms.
