Shiba is reliable for long term but that doesn't make shiba a better bitcoin intact they aren't even close, shiba isn't fully decentralized and bitcoin is, shiba started as a meme coin and now it's going metaverse, the best challenger is doge coin not bitcoin
In the long run I see shiba is not suitable for that and it's too risky too,
for me top alctoin is still the top choice for long term and it's much safer,
let's see what will happen to shiba in the future
