Yes this is true and lack of support for multisig can definitely interfere. One impressive thing about nxt is that its codebase differs greatly from BTC. Different isnt always better though. I would be much more quick to support coins that make crypto easier like Node or highly creative endeavors like Huntercoin. Hell, even Gridcoin never got the attention it deserved. People buy Bitcoin because they worship the dollar and thus BTC has the highest dollar value and the most security. They dont buy Bitcoin because its the "best" coin. If anything, it technologically is one of the worst. Its slow and hasnt included any of the most useful patches since they are afraid to fork. And just like MySpace was replaced by facebook, Bitcoin will be replaced if it refuses to improve its technology. Their "slow" paced improvements on protocol that rely on feedback from part time devs will get slammed once a real serious attack happens like botnet sybil attacks or quantum computers.

Furthermore if a serious company like Facebook or Microsoft came out with a coin (or a country makes its own coin like Venezuela) then perhaps Bitcoin will fall way behind.

On the other hand, ive been talking to some friends and we think Bitcoin may go on another bull run.

Also one of the arguments I had against nxt was it was a "middle coin" and it has been proven that decentralized exchange doesnt need a middlecoin. Examples are atomic trading (once enough coins get checklocktimeverify) or simply Halo microtrading such as in NightTrader.

However, the crypto space is overly competitive as it is and personally i think devs need to collaborate more instead of insulting each others projects. So in reality even though i have my own opinions on coins, i wish them all the best. It gets tiring to hear devs "looking" for reasons to say something negative about other peoples projects. Instead they should be saying "good job!"

Normally, I will openly support projects that have dedicated development. So to all the coins who work hard to develop "good job" and I hope they also see what we do here in Halo and that they clone some of our techniques to make their products stronger. This space will only succeed if we all work together. Because an outside investor can see the toxic environment of bitcointalk and run for the hills (they wouldnt really know the difference of the coins being new to the space).
