Nothing much , IMO We just need bigger blocks to go mainstream and with going mainstream the price will increase logically ... also more anonymity won't hurt (Hopefully developpement of Darkwallet will finish) .
admited;
hort-term, “kick the can down the road” fix. It is ugly, but necessary.
Bitcoin isn't backed by any kind of big corporation, and this is why it has slow development, along with the consensus-first policy.
However, bitcoin needs an industry-grade developer team to catch up with consumer needs.
Many proposals aim to improve scalability, like Lightning Network, but they are way too far from implementation stages. So a block increase is required and as there are infinite ways to increase the limit, there are infinite many different opinions, making consensus almost infeasible.
So don't tell me bitcoin doesn't have it's issues. If you think it doesn't, you can freely buy some "incredibly cheap coins" at 220$ per coin right now.
lose some of your coins just for nothing because others are stealing them,.
