•What do you think is the next big thing? by means bitcoin is getting higher and people should now invest in like what they did before.
•What coin like bitcoin you should invest in? is it bitcoingold? or the next coin that the developers will create
None of the existing ones. If there was a real "next bitcoin", im pretty sure we would already know and we would have the smart people noticing about it and buying it big time. But there is no such thing, only experiments that simply don't cut it.
If you factor in the pros and cons, Bitcoin remains the best project out there. For a coin to take Bitcoin's spot, you would need a complete, total new iteration of technology, and I predict this would take decades, if not 100+ years.
