I've only really started learning about crypto and I don't really see the point to all these million different exchange tokens.
Most of them just seem to speculative tokens with no actual function as far as I can see 
What do you think?

My Coinbase account has been restricted a few days ago so that I am unable to trade or withdraw.
When I log in it asks me to verify my account with identification. I've done this by my account is still locked, and sent an email support ticket and message on twitter to their support but no response.
I was able to log in and view my portfolio just not withdraw or trade until today but now today I get an error message when I log in so I can't view my account at all.

From searching online I came across this article which shows many people have had the same experience.

Has anyone else on the forum had an experience like this with Coinbase?

Do you think we are going to see a huge boom market to something like 200k Bitcoin in 2021 or 2022 followed by a gigantic crash to something like 40k Bitcoin?
I think this is very much possible.
This is what happened in 2013 with boom to $1000 Bitcoin followed by huge crash to $200 Bitcoin, and in 2017 boom to $20000 Bitcoin followed by huge crash to $3000 Bitcoin.
Some people speculate cycles are related to Bitcoin halvening events which happen every 4 years so it would fit the pattern of history if this is what happens.
And once Bitcoin hits ATH many people seem to get FOMO

Whats your opinion of rebase coins?
I have a feeling they could really boom huge like a fad in a super bull run if we get one like in 2017 in 2021 or 2022.
I suspect many people new to the space, who don't even understand Rebase coins and just see the number of coins in their wallet going up will think they're cool, and FOMO into them.

On the other side of it I actually don't see any real practical use for them, and they don't really seem to do what developers imply they're intended to imo.
They essentially just shift the volatility away from the price of the coin to  the supply, which fluctuates instead, and the value of your holding will simply go up and down according to its marketcap just like any other coin.

In terms of centralized exchanges do you think it would be better to use ones not based in the US now?
I'm thinking of avoiding Kraken and Coinbase completely now and just using ones not based in US such as Binance, Kucoin, Huobi.
Btw I'm not personally a US citizen and the KYC rules and regulation on transactions the US government doing seem like a huge hassle now, so would be good to avoid that.

I'm relatively new to the crypto space and have been looking for good low cap coins to invest in, and came across this project.

"Alchemy pioneered an all-in-one hybrid fiat and crypto payments system for businesses which can be deployed in any existing mainstream systems, be it offline (POS, payment terminals, mobile devices etc.), online or in-app to accept payments via fiat mobile wallets, cryptocurrencies and credit cards."

It only has 5 million marketcap, has been in development for a while and I think it looks like a good project from their website https://www.alchemytech.io
So what do you think?
