Then why you wanted to convert that Bitcoin to altcoins when you are planning "IN THE FAR FUTURE"?
bitcoin is the best currency if you are planning long term and also try not to have comparison to this 2 currency , if you really wanted to put money in altcoins then better to divide into Solana and Ethereum each have 1 k .
then from there you may have 2 options of making money in the coming years.
There is not doubt that Ethereum and Solana are good and money making coins so I think changing of some bitcoin to buy Ethereum and Solana is not a bad idea if a person has no remaining amount for investment.
Both are preferred more and if you do investment in all of these three coins like Ethereum, Solana and bitcoin then your future will be bright as all these three coins are more money making these days.
In current years these are going successful and they will be more successful if the Bull season remains for longer time because more bitcoin surges in price more Ethereum and Solana will become successful.
