Ich habe auch schon bei Lieferando mit BTC bezahlt. Es war keine Verzögerung bemerkbar. Ich weiß sicher, dass man in der App mit BTC bezahlen kann. Auf der Website von https://www.lieferando.de/ und der mobilen geht es glaube ich nicht. Ich bin mir nicht sicher, ob Lieferando die BTC-Option in der App nur Stammkunden anzeigt. Wäre logisch, weil dann das Betrugsrisiko für Lieferando geringer ist.

Andere Onlineshops, die ich regelmäßig nutze, nehmen die BTC-Möglichkeit als Zahlung nach einiger Zeit häufig wieder raus, wenn sie nicht häufig genutzt wird.
Beispiele:
https://store.steampowered.com/
https://mach-dich-wach.de/
https://www.egifter.com/ (die haben es zwischenzeitlich aber wieder reingenommen, auch ETH, XRP, etc...)
Dagegen prüft Amazon die Aufnahme von ETH und hat dazu auch schon Domains gekauft (siehe hier: https://www.btc-echo.de/amazon-sicher-sich-kryptowaehrungs-und-ethereum-web-domains/ )

Deswegen gilt: so oft wie möglich mit BTC bezahlen, dann klappt es auch mit der Adaption. Dafür bin ich auch bereit, ein paar Cent Gebühren zu zahlen, solange es hilft 

Most trading platforms want money from you before you even start to trade. Apitrade just charges fees for successful trades. I think it's a win-win situation. Crypto Hopper f.e. charge a high fee for a decent monthly plan. If you want to trade with small or medium amounts, Apitrade is better, if you have very large amounts and trading knowledge, I can recommend Crypto Hopper.

Well it is not my intention to make money out of somebodys loss. That is the reason why I did not recommend Crypto Hopper

Well, it feels like crypto spring is starting. In the side market profits start rising again. I am still using Apitrade and it is generating decent earnings every day. On bad days there is less activity but when the market rises the trades rise too. I can still recommend trying it 

Why would you not invest in altcoins? I understand you don't like copy & paste coins but what about blockchains like f.e. Steemit? It's really unique and has a bright future.

Many people think that some altcoins are better because of the scalability. Please remember that decentralisation is a point that small projects can not realize as there are just a few big whales. Bitcoins decentral structure is far more developed than any competitor. Just take a look at Bitcoin cash, where more than 50% of mining power is in the same mining farm.

The gap between both is not as big as before but don't forget that new second layer solutions for ETH are coming next year. More ICOs will be made on ETH blockchain again if the scalability problem is solved.

It would be interesting to see some ATMs with low fees. All machines I know charge a high fee so that there is no advantage vs. an online exchange.

Update 3:

Since we are clearly in a bear market and the BTC dominance went up very strong, my Apitrade portfolio had some trouble making trades as good as in the side / bull market. Nevertheless, the bot is still making good trades every day.

Always remember that the bot does not sell with loss. It keeps a position until it can be sold with a profit. In bad market stages it takes longer, in good ones it is very short and the profits are high.

Even though the last days were hard for the crypto market, I do not regret having my Apitrade bot active.

Update 2: Last days were not so good on the crypto market. The bot remained stable and did not make losses, just the profit was very low the last two days. But anyway, I think it made 0,1-0,3% even with that bad market.

The arbitrage part of the bot also works well. On my four exchanges it manages to make about 10-20 arbitrage trades all with a small profit per day. On good days even more

In my opinion TA is useful for the crypto market but we need more steps to make it easy to use. I have tools like CryptoHopper and you can make good profits from it - mostly in side markets.
Be very careful in order to not loose money. I have experienced that is is often useful to look up your strategy in the trading forums. On some days I even made 1-2%. But when the market goes down very fast you should have a good trigger 

Waiting for McDonalds payments in BTC too 
And of course LN will fix the high fees hopefully.

In my opinion Bitcoin's success depends on wether second layer technologies can solve the scaling problems. Lighting Network has made big steps in the last months. I am sure there will be even better solutions in the future 

But watch out when buying from any amazon marketplace. Better buy it directly from Ledger and be sure that the ledger has not been used before. Otherwise it could be manipulated and someone could steal your cryptos.

Right, let's not panic today and HODL. Prices will recover soon - with even better news.

I got my ledger without any problems directly from the website. Payed with Btc.
