wow it will take me almost 1 week to finish the download i suppose rofl or even more than that
And that's the problem, not everyone will be able or willing to download the full blockchain. True decentralization can only be achieved if everyone has the same opportunity to download the full blockchain, if only rich countries can afford to run a full node, already it's the beginnings of centralization. Basically back to square one.
Yes it may become a problem. And the problem of bandwidth is much more pressing than that of storage, because most people in the industrialized countries are greatly overestimating the real upload speeds available worldwide. Many providers - even in countries with very good infrastructure - have explicit or implicit bandwidth limits and in many developing countries, sufficient bandwidth is either not reliably available or extremely expensive (sometimes even at Western standards - without taking into account the significantly lower buying power of the population in these countries).
So to preserve decentralization, Bitcoin must be scaled in the least resource expensive way possible. In my opinion, segregated witness and lightning networks are a step in the right direction, because they address the issue of microtransactions in a responsible way. Trying to store all transactions into blocks in the current format by allowing unlimited block sizes would be the end of a decentralized Bitcoin network.
ya.ya.yo!
