You posted any important post bro, but you didn't share your contacts info. How can I get you?

This article fails to mention key information such as the fact that some of these wallets don’t support the forks. That, besides security, is arguably the most important information. Harold Burton

You are putting out some GREAT videos that are very informative to a newb, like me, in the cryptocurrency market. I just began investing in cryptocurrencies a week or so ago. I currently don’t have a large sum of money in the market and have all my coins in exchanges for the time being while I figure out what type of wallet best suits me. My thought is that a paper wallet will be my choice based on the fact that I am planning to hold on to my coins for some time. I do however like the idea of a desktop wallet for ease of use and the portfolio option but I can also use a portfolio app. I also have a handful of altcoins like ada and xrp that don’t appear to have any desktop wallet options. If i go the paper wallet route, is there a transaction fee every time I transfer back to hot wallet? Also once a paper wallet is established, is it just a matter of sending purchased cryptocurrency to the established public key to transfer the coins there? Can I create paper wallets for these altcoins? Thanks again in advance for your reply and I’ll continue to educate myself with your videos and content. Ashley Jones

If a site goes evil or disappears, since your using their software, tech, wallet etc. How are you to recover your cryptocoin? Which tech systems will protect from this scenerio so you can use others if your chosen tech goes bye. Joseph Donahue

Hi, Thank you for the Review. I’m a newbie when it comes to cryptocurrency and your website really helped me alot. I want to invest on some top altcoins, as of now I have LTC, Dash,Doge, XPR and BTC. Based on your review above, I think I can use exodus as my wallet but i just have a quick question. It’s alright to uninstall and reinstall it to a different computer/laptop right? and can it be downloaded and open simultaneously to two different computers? I’m sorry , i’m really noob.

Your Bitcoin wallets review was so helpful. I have read a certain comments and you say that Exchange-Wallet web service it is not good idea, because all risks it can have. In that way, what do you think about SpectroCoin services. CrazyAsk
