We are more focused on bitcoin than ever as most of the users wants to invest into bitcoin assuming a bull run post halving but nit many are planning to invest into altcoins, I think we need to focus on altcoins as well as there are coins like Tron, ADA and all which can pump anytime and priced extremely less as of now and even if bitcoin pumps it will have positive affect on altcoins as well so I think we should invest into reputed altcoins as well.
Of course the best purchase of a good coin is made only at a pre-sale. But getting to that sale is not easy. Now I think there will be a fly to the moon of previously undervalued projects, those coins that sell below ICO. Of course those that are doing something for their project besides managing the market. For example Near.
