It is better to know what platform suits you, knowing the difference on both platform is important. Try to do a research about those two and gain some knowledge about it. But it is all about the technique and experience when it comes in trading.
That is too high buddy. Even all altcoins value combined together will not reach that huge price. In bitcoin, that would be impossible from two years. It is still fighting against 10k to 20k usd and since then, we haven't seen bitcoin to break to more tha 30k so no that 100k thing is not gonna happen.
Interesting. I anticipate that the price will hover around about 13k for a while, and then probably won't fall below 10k in the future. These reports help to give us a picture of what the price might be after the halving.
Asides being a very good trader with the ability to do some good analysis, news, most especially in the crypto world are very necessary as they can help make some pretty good decisions faster. It has helped me over the years and where I learnt my lesson was when I bought into a coin that was being delisted on one exchange and that made me to stop buying any altcoin anyhow without being sure from the news that is Okay to go ahead.
