Please house, I will like to know whether out of the existing altcoins anyone of them has potential to be like bitcoin in the nearest future. I will appreciate if i can know the reason why because this will greatly assis me in planning my investment strategy. Thanks.
For planning investment strategy you should make your portfolio diversified.
Bitcoin is a real gold but certain Silver are in the market.
Bitcoin is Number 12. Litecoin: faster block generation rate and faster transaction confirmation.
3. Etherium: Decentralized software platform that enable smart contracts
4. Ripple: real time global settlement network that offer instant, low cost payment.
5. Zcash: open source crypto launched in 2016.
6. Dash (Originally known as darkcoin) more secretive version of bitcoin (as peer sources)
like bitcoin literally,only BCH or bitcoin cash at the moment

its a copy of bitcoin with few adjustments
if you meant pricewise,then I don't think any coin will substitute bitcoin at number one spot for quite a long time,at least several years
the closest ones would be Etherium and if you want to plan your investment strategy
take a look here:https://coinmarketcap.com/ or pick any similar website
you can see that Eth is second in capitalisation,while Ripple being third is not exactly a decentralised cryptocurrency as it is supported by banks
if you plan to invest,you can go for relatively unknown,risky coins that may follow bitcoin's footsteps and increase in price over years
