As long as my research for long-term investment I personally suggest a few coins
 It has Ethereum, Shiba Inu, Matic,... 
Ethereum is a class coin that is known for its sustaniable Blockchain technology & the largest smart contract platform. Their rank in the marketplace is 2nd in the future it will explode.
Shiba Inu is the top meme coin that has performed well & now Shiba Inu is among the top 20 best coins at the market place & taking huge gains since launched. Shiba Inu is the top crypto to invest in in 2022
Matic is the best coin for long-term investment. Matic is used for transaction fees staking, etc so it is the best investment for long term.
I am not a financial advisor but it's my opinion.
