Yes , i'm new at this , but i have more than 15 years of experience in the financial market, the Crypto will be just 5% of my portfolio...
From where i should start ?
How i can actually invest in those cryptos ?
I'm not sure if 15 years of experience in the financial market will help you all that much in the unregulated clusterfuck that is crypto. The normal rules don't apply I'm afraid.
Things to read up upon, apart from how Bitcoin and other crypto-currencies work of course:
1) Which exchanges are reputable (Kraken, Bitstamp, Coinbase come to mind)
2) How to keep your coins safe (cold storage: paper wallets, hardware wallets such as Trezor or Ledger)
In addition, keep in mind the following:
3) DO NOT keep your coins on exchanges for safe keeping
4) DO NOT blindly trust people trying to push alt coins such as Ethereum oder Ripple on you. Do your homework and come to your own conclusion.
