Well, maybe your issue is just a browser-related issue have you tried to access it with different browsers and devices?
If not try it first but if it doesn't still work instead of using a VPN(VPN is not safe) to bypass some blocked things from the internet you can change your device's DNS to Cloudflare DNS and try to buy these coins again update here if it didn't work.
And since you already have access to Coingecko have you checked the list of exchanges under that coins?
If you can buy other crypto on Binance why not buy USDT and withdraw it from Binance to non-custodial wallets and buy Notcoin or Bookofmeme from DEX those exchanges don't require KYC.
Can I rule out browser issue if I can access other altcoin trading pairs on binance but not these 2 coins I mentioned?
The DNS trick is separate to the VPN or VPN must be on while changing DNS also?
Yes I see the other exchanges that list the same coins but its the hassle of registering with them and completing KYC with them otherwise if I deposit cash into these new exchanges that I signed up for then there's a risk of these exchanges freezing my account. Also these exchanges I see on CoinGecko I never heard of them before and it doesn't say on CoinGecko whether they will accept UK customers? Or please kindly share who is the biggest most popular exchanges that have the most trading pairs & listings for UK customers?
Which non-custodial wallet you recommend because I have lost nearly $1000 in a non-custodial wallet in the past because I withdraw from exchange to my own wallet. How this happened? I withdrew an crypto altcoin from exchange to my own wallet that I planned to Hodl for the next bull market, it sat in my wallet safe, I wasn't hacked or anything. Then when the bull market came the altcoin dropped to $0 because there was 1:1 swap for a newer version of the coin that had to be swapped by a certain deadline otherwise if you don't swap the coin the old version becomes worthless. I missed this. By hodling it in my own wallet, my own wallet didn't notify me of this upcoming swap or deadline so basically I was hodling a worthless coin in my own wallet that I didn't knew about. Had I left this coin on a exchange like Binance then Binance would have notified me by email of this upcoming swap or Binance would do the swap for me automatically because I have no time to manually check the latest news of a altcoin that I bought via google search everyday. This risk does not happen with bitcoin because with bitcoin you can sleep at nigh easily but with altcoins you need to be constantly updated on the latest news to avoid losing money this way. From this which multi-crypto non-custodial wallet do you recommend that keeps the wallet owner updated on the latest news & notifications within the wallet app of the altcoins that are in that wallet?
It is only worth Hodling Bitcoin in your own wallet. Other altcoins best held on exchanges not in your own wallet. Even with for example Ethereum, when Eth moved to POS from POW there could have been a coin swap by a certain deadline for the newer POS coins. If for example I kept $1million worth of Ethereum on my own hardware wallet, my hardware wallet didn't notify me of this swap for a newer version then I would have lost $1 Million So from this I ask again which multi crypto hardware wallet or software wallet notifies the wallet owner via its app of upcoming altcoin changes or swaps and which wallets that you control automatically does the swap for you
With DEXs, the fees are higher right because they have lower liquidity?
