what problem do you have in bitcoin.
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) .
Thats much, because bigger blocks = bigger upkeep costs for full nodes so less secure = less value.
U forget that aspect.
So more anonymity, bigger blocks and ALSO better scaling.
3 main points thats bitcoin need.
