“[…] IOTA and VeChain, on the other hand, provide fee-free platforms. IOTA does so using its “Tangle”. The more people that use the IOTA network, the faster the network becomes, potentially having infinite scalability.
On the other hand, VeChain, which is a Blockchain-as-a-Service (BaaS) network, leverages the blockchain to provide a trust-free and highly scalable platform. By having higher throughputs, both coins are well-poised to continue penetrating the market as more projects are taken up.
The potential for exponential growth is with the altcoins due to this, even if Bitcoin were to scale higher after implementing Lightning Network.”
