After surfing through the good side of BItcoin I was asked to give reasons why bitcoin won't last by a friend I searched through the web and found the following
1: Exposure to Bitcoin-Specific Scams and Fraud.
2: Black Market Activity May Damage Reputation and Usefulness.
3: Susceptible to High Price Volatility.
4: No Chargebacks or Refunds.
5: Potential to Be Replaced by Superior Cryptocurrency.
6:Environmental Ills of Bitcoin Mining.
7: Bitcoins Are Not Widely Accepted.
8: Wallets Can Be Lost.
9: Risk of Unknown Technical Flaws
10: No Physical Form
Guess what non of those mentioned above was big enough to discourage my friend from joining Cryptocurrency (buying bitcoin).
Which of the following disadvantages are you afraid of and how do you think it can be resolved
Well I will leave my opinion on those concerns. I guess that some are legit, but most of them should not really steal your sleep.
1: Exposure to Bitcoin-Specific Scams and Fraud.
Makes no sense. Bitcoin itself is not a scam, so you shouldn't judge ICO scams, or any other projects that use bitcoin and turn out to be scams. There are plenty scams with fiat as well, and you are not concerned that fiat will disappear. People need to start separating what is bitcoin and what are projects that use bitcoin as a currency.
2: Black Market Activity May Damage Reputation and Usefulness.
Same as above for reputation and black market activity. As for reputation and usefulness, bitcoin has a great team behind it, and it's practical cases can't be denied. I won't mention them because there is plenty information about it already. I think you should see bitcoin as insurance for a world crisis, because it has value and is decentralized.
3: Susceptible to High Price Volatility.
True, but that can't last forever. If adoption occurs that will stop because the liquidity will be huge, so less volatility.
4: No Chargebacks or Refunds.
Don't really see a problem with this one.
5: Potential to Be Replaced by Superior Cryptocurrency.
Technology keeps evolving so that can happen to everything. But even land mail wasn't completely replaced by email, so you can't really tell what will last and what it will disappear.
6:Environmental Ills of Bitcoin Mining.
Environment is a global concern and not just a bitcoin problem. If you think about, gold and fiat are more harmful to the environment than bitcoin, so this is actually a point in favor for BTC.
7: Bitcoins Are Not Widely Accepted.
True, but BTC is just in it's early days. It needs to solve a lot of issues first. See BTC as a beta product, and evaluate it's potential as a full product. I would say it's a really good investment.
8: Wallets Can Be Lost.
A lot of valuable things can be lost. This is not a bitcoin problem. Even money on banks is not 100% safe, so you can't really go that way.
9: Risk of Unknown Technical Flaws
The same as above. There are no 100% bullet proof products.
10: No Physical Form
Actually there is at least one project that created a bill version for bitcoin. They are normal bills with values from 0.005 to 0.01 BTC or something like that. They have a chip that is made by samsung if I'm not mistaken, and they are just that. Bills that have bitcoin in it. Not sure we really need that, but it can be done.
